Please give this a high priority for fixing. This affects thousands of users in the U.S. who require dosemu in courts throughout the country.

Uhm the patch you posted here doesn't make a lot of sense. This would have been on Karmic and its 2.6.31 based and the patch was applied to 2.6.29-rc1. Also, I verified that its contained in the source when I pull do an apt-get source linux-image-2.6.31-14-generic. So I'm unsure how I'm supposed to try that patch.

Hi David,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 455067

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

This is fixed by upstream 6554287b1de0448f1e02e200d02b43914e997d15. Can we include it in the next Lucid kernel update?

Reproducer, on i386 kernel, with vm.mmap_min_addr=0, thanks to Bart Oldeman:

Create a debug script file (e.g. debug.scr) in ~/.dosemu/drive_c, that is, dosemu's c:\

---snip---
a
nop
nop
int 3

t
g
q
---snip---

Then run
dosemu "debug < debug.scr"
This will get both int1 and int3 active.

Try it a few times, it should trigger the bug in "dmesg".

Hi Tim, sorry I took so long with this. I've reproduced the original crash (it just kills dosemu):

[ 167.120539] note: dosemu.bin[1623] exited with preempt_count 1

However, when running this with the test kernel, the entire system hangs, so that's no good. :)
