Bug#667434: lvcreate / lvremove snapshot under Xen causes Kernel OOPs

[Quintin Russ <quintin@quintin.co.nz>]

Hi Ian,

After around 26 days of uptime one of the first hosts we upgraded the
linux-image-2.6.32-5-xen-amd64 package to 2.6.32-43 from
proposed-updates crashed overnight in the same situation as originally
detailed in this ticket. One new piece of information has come up since
then - just prior to it crashing this was logged into syslog:

May 16 01:16:20 dom0 kernel: [2332024.578498] lvcreate: sending ioctl
1261 to a partition!

I am going to look into setting up a serial console for our nodes now,
but just highlighting that I don't believe this update has fixed the
issue we're seeing.

If you have any other ideas / thoughts on how to reliably reproduce this
fault please let me know.

Best Regards,

Quintin
