I think Jamie Strandboge is on to something in comment #18 (even though
Kees Cook reports something contradictory in #28).
I have a very similar wifi chipset, and if i disable wifi the problem
appears to be gone. At least my VM successfully compiled a whole
kernel, which it's never done with wifi

In my experience, apt-cacher-ng is a flaky crock that crashes all the
time. I'd guess it's not related to this bug.

I'm affected by this bug too.
I recently upgraded my laptop from a Dell Latitude D380 running Lucid
64-bit to a Dell Latitude E6520 running Natty 64. I moved all my VMs
from the old machine to the new. All the VMs had been working fine for
a long time on the old system.
The first VM i booted is

@Kees,
what sort of system do you have?
I was actually wanting to ask Jamie to do something like
10 or 20 parallel jobs doing wget, tar xvf, and
diff -nrup linux-2.6.37.tar.gz, wgetting from a local
mirror and looking for differences or segfaults.

Looking through the changelog for the wireless driver (assuming this is

At this point I'm afraid the most likely path to figuring this out would
be to take the upstream kernel, reproduce it on there, and then bisect
from 2.6.35

Ok, after one run with ext3, plenty of room, no ecryptfs and using
wireless, I have the instability. I do not have any kernel messages
related to this, and ifconfig shows no errors.

So after clearing some space and running the identical test I did in
comment #19 I had no errors after 64 runs. So without ecryptfs and with
wired networking it seems ok. I am going to run the same test but with
wireless instead of wired and see what happens.

I still don't think it is the hard drive because a) it is a pretty new
intel SSD drive (less than one year), b) I am not getting any other
errors outside of kvm (fscks are clean, not file corruption, nothing in
kern.log) and c) rebooting into the maverick kernel does not exhibit
this problem.

So at this point possible culprits seem to include: ext3, aufs, and the
kvm_intel module (and your hard drive)?
Do you have space in which to try on an xfs filesystem?

Hi Serge,
Yes I am still having this problem. I have not tried to reproduce on
another machine because I don't have a natty installation that can do
kvm anywhere else. I have not yet tried outside of ecryptfs, but will

Hi Jamie,
are you still having this problem? Have you been able to reproduce on

Ok, no aufs kernel tracebacks (ie bug #621195) and the guests are flaky.
What is triggering it is a maverick dist-upgrade in one guest, and an
'apt-get install ubuntu-desktop' in another maverick guest, that only
has ubuntu-minimal installed. I will try disabling ksm.

Meh, strike that last comment. I had tracebacks due to bug #621195 in my

Well, I just had a segmentation fault and other weird behavior in a

and that the maverick kernel is still ok.
