I use a old version LVM2 2.02.98 on kernel 3.0.101, I encountered such a problem.
The detailed steps are as below,
I am doing an update with the following strategy for updates
make LVM Snapshot of root ("/") file system partition
Run zypper updates ->
Run a script to check certain stuff is OK ->
On failure of that script (if any of the check fail, e.g one rpm update failed), merge LVM ->
Reboot (because you have to for an LVM merge if it's the root volume)
And then, sometimes as the system comes back up, Reiserfs sometimes goes read-only / corrupt.
which shows in the dmesg as

Did you meet this problem? this problem was fixed in the latest version?
Thanks a lot.
