Re: [linux-lvm] Snapshot causing segault

Thanks Milan I believe you are right about it being a bug. I was able to trigger the panic with the script provided and the results are very similar (although I'm now having a hard time recreating my problem on demand).

I should have fun finding this kernel for SLES10 SP4 even though the minor is only 2 off...

Thanks again for everyone's help.

This is almost surely kernel bug, not userspace one.

It is very old kernel, so hard to say exactly which patches are needed
but my guess is it is very similar to https://bugzilla.redhat.com/show_bug.cgi?id=360151
(note: fixed 2007!) with upstream patch

(But there can more patches, this is really old and someone need
to do proper analysis what is going here.)
