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 On Saturday 04 February 2006 18:43, Ed Tomlinson wrote: > I need some help figuring this one out.

In 2.6.15 + reiser4 2.6.15-1 works fine - the resiser4 filesystem is heavily used with > no errors. Smart report no problems with the drive being used.
