Thanks. This helps some, but I'm not sure why it should fail there. Possibly a memory corruption problem caused by a bug in an earlier error path. > With your two patches applied, I now got this: > > ERROR: (device loop0): remounting filesystem as read-only > blkno = 200000687, nblocks = f > ERROR: (device loop0): dbFree: block to be freed is outside the map > BUG: unable to handle kernel paging request at 338f8038 I see I've got a few of these to track down.

But I don't mind testing either :-) Can you please send me a copy. For some of these, I'd like to get a repeatable test case, so I'm not debugging several problems at once.
