I just got the below oops while working with a newly upgraded SUSE 10.1 install.
It uses a 2.6.16.13-4 Suse kernel and lvm2-2.02.02-9 userland.
I was attempting to work with a LVM snapshot at the time.
I have not yet attempted replicate this with a 2.6.17 kernel.
I assume the below is related to LVM snapshots?
thanks,
Greg

Please ignore.
My issue was resolved by upgrading to the current SuSE test kernel at
ftp://ftp.suse.com/pub/people/aj/10.1-kernel-update-test
2.6.16.21-0.6
Sorry for the noise.
