Bug#294826: kernel-image-2.4.27-1-686-smp: kernel panic in dm_snapshot.c
Hi Alex,
thanks for your bug report. Sorry for the long delay in replying.
Long inbox...
I took a quick look into this. Unfortunately I can't find dm_snapshot.c
in either the kernel tree or the evms source code tree, nor anything
that looks like it. Do you have any idea where it is?
I also took a quick look through the bitkeeper changelogs for
2.4 and 2.6, and can't see anything tagged EVMS since August 2003.
So no fun there.
Unfortunately thats about as far as I can get without devoting
a lot of time to this. If you have any additional info, please
send it here as it comes to hand.
