[linux-lvm] LVM2 snapshots on root fs

we are using lvm (lvm version 1) snapshots for backup purposes for some
time without any problems. 

Whenever I try to create a LVM (version 2) snapshot of the lvm
containing the root fs my machine crashes. I am using SuSE 9.1 (kernel
2.6.5, lvm2-2.00.15, device-mapper-1.00.09), but I also tried a unpatched kernel with the redhat lvm2-2.00.21 and device-mapper-1.00.19
rpms. Same result... I can't create snapshots of the lvm with the root
fs, other lvm snapshots are ok.

Is this a known lvm2 problem? If it is a kernel issue, are there any
