First, thanks for this great filesystem. Been using it for years
without probs, so I hope it gets integrated into the mainline soon.
However, I'm having some problems after upgrading from kernel 2.6.31.6
to 2.6.33. This is a 64 bit gentoo-patched kernel (just patches for
stability, I believe - no new features), with the reiser4 patches from
Edward's site. It's happened to me twice now that my X session locks
up and I see the following in my logs:
Mar 19 15:05:23 [kernel] WARNING: Keys are inconsistent. Fsck?
Mar 19 15:05:23 [kernel] reiser4[gconfd-2(6033)]: cbk_level_lookup
(fs/reiser4/search.c:963)[vs-3533]:
Yup, I know about this problem. I think this is an old bug which was
sleeping and has woken up after mainline upgrade to 2.6.31.X
I remember that VS pursued this bug with partial success right
before leaving 2.5 years ago.
This is reproducible for me and I am trying to narrow down the
problem.
This is a situation when trying to insert a key
{el = {22136708, 20075163819723075, 1384069, 131072}, pad = 22136708}
Insert position in the node is correct, but its right neighbor
has wrong value of ld_key:
