[Virtual-pkg-base-maintainers] Bug#615048: base: After removing lvm snapshot got kernel BUG at /build/.../source_amd64_xen/arch/x86/xen/mmu.c:1649!

Fri Feb 25 08:06:35 UTC 2011

Package: base
Severity: normal

Problems's started after changing version of Debian from Lenny to Squeeze.
I'm using Xen with virtual hosts on LVM volumes.
I make a snapshot of LVM volume and dump it to a file.
After it I'm tring to remove snapshot.
The operation fails and generates kernel error.
After the error one of cpus is used in 100%.
Neither shutdown(reboot) nor use many other command because seems like the system is high load or hung up.
The same is on two other machines (I've got two HP DL360g5 and one DL380g7).
