Hi,
2.6.16-rc4-mm1 panics with a zam-597 (fs/reiser4/txnmgr.c) with an rc=-5
This has been happening since 2.6.16-rc1-mm2. It makes testing with reiserfs4 impossible here.
I have not been able to figure out how to use bisect etc to find out what is triggering this. I had
hoped that reversing "jbd: split checkpoint lists" as per the fix for ocfs2 might help (its in rc4-mm1)
but no such luck.
Does anyone have a suggestion on how I can help find what is broken here?
TIA,
Ed Tomlinson
