Package: lvm2
Version: 2.02.06-4etch1
Severity: important
When trying to pvmove from one PV (/dev/md0) to another (/dev/md2), it
crashes and causes a kernel panic. Both PV's are a member of the volume
group 'data' with logical volumes 'user' and 'stuff'. There is another
(uninvolved) physical volume, /dev/md1, which is also in the volume
group.
I'm reporting this against my current setup of etch, but I've also had
this issue on the same machine with etchnhalf and 2.6.26-1 kernels.

Kernel crashes are always kernel bugs. As no information came up within
years I'm closing this bug.
