Crash on coLinux start

Lorne Sturtevant — Wed, 28 Mar 2012 19:36:19 -0000

coLinix is crashing when it's starting. My machine is Windows xp SP3. The crash only occurs when using a PAE kernel. If PAE is disabled, then it will not crash. I am using the 0.7.9 release and the Debian-6.0.1-squeeze.7z image.

This crash is not consistent. I've created a little script that starts coLinux, waits, then kills it. It does this in a loop until it crashes. It will eventually crash, but it can be from as little as 10 tries upwards of 174 tries in the loop. I've attached the script, it's test.sh. I run this under cygwin. I've also tried this on two separate boxes, both are winxp sp3 without PAE. One box seems to crash quicker than the other, but they both eventually do it.

I've attached one of the minidump files. From examining the dump files in windbg, they all appear the same. The crash is in a thread that's not running linux.sys. It always crashes at the nt!MiFreeInPageSupportBlock+0x2a.

Let me know if there's any more testing/information I can gather to track this down.

rmdir on cofs returns success but the dir is not deleted

Grnch — Wed, 21 Mar 2012 09:28:08 -0000

I shared a local NTFS disk through cofs (host is XP) and then I mounted it from inside the Linux image with the following mount options:

noattrib,nocache,uid=foo,gid=foo,fmask=0644

Then I navigate to the mounted cofs dir create a non-empty dir, e.g.

mkdir foo
echo bar > foo/bar

If I try to delete this dir with rmdir, instead of getting an error that the dir is non-empty, I get success but the dir still remains.

rmdir foo

Of course, "rm -r foo" will get rid of the dir, but the problem is that the rmdir() system call doesn't return an error for non-empty dirs, which confuses some software when using cofs shares from coLinux (notably CVS).

coLinux version is: 2.6.33.5-co-0.7.9-r1547

Swap file in Debian image is lost

Stas Degteff — Mon, 16 Jan 2012 15:13:24 -0000

Archive Debian-6.0.1-squeeze.7z contain swap_128mb.img with size 45 bytes instead 128Mb, this is text file with one line: "/data/Download/coLinux/Debian6/swap_128mb.img". After unpack an archive and run squeeze.bat I see in the colinux console red error message about invalid swap device, and boot continues.

Solution:
update squeeze.conf: ann a line "cofs0=.\"
boot, login, run commands:
mount -t cofs 0 /mnt
dd bs=1M if=/dev/zero of=/mnt/swap_128mb.img count=128
mkswap -f -L swap_128mb /mnt/swap_128mb.img
reboot

Colinux Crashes using NDIS network mode

bob_wh — Sat, 07 Jan 2012 20:18:44 -0000

Hi:

I have been having problems with blue screen crashes when running colinux. They are usually memory corruptions, irql too high, corrupt page table list. The just started when I tried to get ndis bridge mode networking working on Portable Ubuntu which uses colinux. I never had any crashes when using the slirp mode networking. Also, I never have any crashes when colinux is not running. These crashes occur on WXP with all service packs and updates applied.

Many dumps had Kaspersky driver active at the time of crash.
Kaspersky support has analyzed the dump and say that their driver
Is not causing the problem. So to prove it, I uninstalled Kaspersky and used their clean up utility to removed all components, and registry items.
It still crashed with memory corruption but this time the active module was nt . The windbg output of this dump is:

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 9ded4804, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation

I am using the stable snapshot of colinux dated 2/16/11
Linux version 2.6.33.7-co-0.7.9 (hn@hn-dt) (gcc version 4.4.1 [gcc-4_4-branch revision 150839] (SUSE Linux) ) #1 PREEMPT Wed Feb 16 23:51:21 UTC 2011

The linux config file:

kernel=vmlinux

setcobd=async
cobd0="F:\P_Ubuntu\Portable_Ubuntu_V4\images\rootfs.img"
cofs0="F:\P_Ubuntu\Portable_Ubuntu_V4"

This crash is fairly easy to create immediately when using XEMACS for editing. However, it takes longer to crash if you are just surfing the web.

Since this is a memory corruption the program/driver active at the time of the crash is the victim of the corruption and it is likely some other driver/program caused it, in this case colinux.

========================================================
Update:

I added /nopae to boot.ini as suggested in the Colinux-users list. It still crashes with PFN_list_corrupt.
I attached a zip of these 2 mini-dump files to this case. I have a total of 17 mini-dumps with this problem.
Can you suggest what to do to get the information that you need to solve this memory corruption problem.
This problem is currently holding up the next release of Portable Ubuntu.

Thanks for your help.
Regards
Bob Wheater

somebody ident src/colinux/user/daemon.c, so co_daemon_load_symbol_and_data, import and "co_info" not same line.
When user set COLINUX_KERNEL_STRIP to yes, you will got an unuseable kernel.

Arch Linux image - can't upgrade

The Arch Linux image can't be upgraded to the latest version of Arch Linux. A more up-to-date Arch Linux image is needed.

crashes on 2gb swap

Anonymous — Fri, 03 Jun 2011 19:42:29 -0000

running xp sp3. crashes "sometimes" -- more often than not -- if swap file is 2g. haven't tried 1g or 1.5, but simply went back to 512 as stated in the configuration file:

# Swap device, should be an empty file with 128..512MB.

works without issues on 512.

/dev/ttySx: " Device or resource busy"

Using simultaneously two serial devices appears to be not possible (colinux 0.7.9).
For example below, ttyS0 or ttyS1 can be read, but if ttyS0 is being read, then ttyS1 is considererd as busy.

root@colinux:~# cat /dev/ttyS0
^C
root@colinux:~# cat /dev/ttyS1
^C
root@colinux:~# cat /dev/ttyS0&
[1] 2618
root@colinux:~# cat /dev/ttyS1
cat: /dev/ttyS1: Device or resource busy
root@colinux:~# dmesg -c

wget'ing something makes audio chirp on host

Anonymous — Mon, 21 Feb 2011 20:02:51 -0000

Hi,

I would like to report a strange thing that I found using colinux 0.7.9-RC4.
When I use an ArchLinux guest and wget something (preferably something large like an iso) my foobar player on the host (Windows XP 32bit) plays chirps through my music (MP3 files). When wget finishes or is killed, it keeps chirping until the buffer is refreshed (typically 0.5 buffer length).
So it seems the audio buffer gets corrupted while it is filled.

But it gets stranger:
- Media Player Classic with ffdshow seems to chirp only when I play an audio or a video file which has AAC or AC3 audio.
- MP3 in MPC is not affected when decoded with the libmad decoder, but does chirp when decoded with libavcodec.
- Rarely I see artifacts in the video while wget'ing.

- When I lower the buffer length in foobar (to 50ms) and start wget, the chirping is instant.
- When I increase the buffer in foobar (to 16s) and start wget, the chirping takes a long while to kick in, but keeps on going while wget is finished or killed.
- Using different output precisions in foobar gave me these results:
-- 8bit + non-dithered: chirpes
-- 8bit + dithered: doesn't chirp
-- 16bit + non-dithered: doesn't chirp
-- 16bit + dithered: doesn't chirp
-- 24bit: chirpes (dithering unavailable)
-- 32bit: not supported by soundcard, sounds awful.
- BTW: My soundcard is a Soundblaster Audigy SE 24bit.

- Firefox on the host seems to crash a lot more when wget'ing in a guest and a flash movie is playing on the host (youtube).
- Rarely I see artifacts in youtube video's while wget'ing.

So I tried isolating the problem:
- dd'ing 200megs from /dev/full to a file. No chirping.
- wget using an external server (linux iso fetching). Chirpes.
- wget using an internal server (binary blob fetching). Chirpes.
- Running netio, client on guest, server on host (tcp using default port and port 80). No chirping.
- Running netio, server on guest, client on host (tcp using default port and port 80). No chirping.
- Using pcap-bridge instead of ndis-bridge. Both chirp.
- Using Debian Lenny guest, I recently upgraded the Archlinux guest and it uses quite cuting-edge packages, Debian should be more old fashioned. Still chirpes.
- Written a little program to do a lot of floating point operations. Doesn't chirp.
- Written a little program to do a lot of memory allocation operations. Doesn't chirp.
- wget using the guest as server (binary blob fetching), no real network involved. Chirpes.
- Download the binary blob from the guest to the host (reverse http transfer). Doesn't chirp.

Seems only wget causes the problem to surface. And it seems to me like a memory corruption somewhere.

Hopefully this rings a bell with someone and can be fixed easily. Keep up the good work.

Greetings,
Keith
