I can do you one more, here are links to, kernel tarball as built by me
(2.6.31.14), its configuration and my xen4.0.0 directory.
Tomorrow i will test 4.1.0 and 2.6.38, allthough i have to say, if one
kernel works and the other doesnt, to me it seems like a kernel problem,
not one of the hypervisor. Of course, since i dont know the inner
workings of xen, that point of view might be ... flawed.
It would be nice if you could define a set of parameters that could
prove beneficial in provoking the bug as it would make it easier for me
to test different scenarios.
Or better yet a script that definitly will provoke it within a given
timeframe.
So far even restarting multipathd _could_ trigger it for me.
It also occured during bootup and when it did it kept on happening until
i did a cold restart of the server.
Does that make sense? Does data remain in the memory modules when i
reboot a system? (init 6)
And if that is so, whats the "Scrubbing memory ....." for that i see
when xen is loading?
One thing i would like to verify is that the bug only occurs when
running the kernel under xen and not when its running on its own.
I cant quite remember if i tried that in 2010.
Today i ran a loop of 300 lvcreate,snapshot,lvdelete on a standalone
2.6.32-xen0 kernel and did not receive an error. I didnt really have the
time to try and catch it that way running under Xen. I will do that
tomorrow.
I will report my findings.
best regards,
