With 2.6.15-20 i386 (32-bit), Dapper Flight 6, JFS is giving equal headaches.

The biggest showstopper appears to be that fsck.jfs does not always detect a dirty filesystem, leading to a 'successful' journal replay in ignorance of corrupt entries.  This is being a particular bear with X.org/gdm-related entries in /tmp, given my machine's tendency to jam itself in odd ways immediately after opening files there.  (See #39333)

Doing a forced check actually cleans things up.

A concomitant issue is the boot process's handling of the case where fsck.jfs doesn't do its job and so a JFS root partition comes up read-only.  Lots of things fail there, obviously, but some truly weird things happen (bash with no job control coming up 'over' a text-gui gdm complaint dialog, other consoles and instances of login seeming to initialize or not at random) ... 

IMHO, the boot scripts should check that all requisite locations are writable (/tmp, /var/log, where else?) and  bomb straight to a shell -- with instructions for continuing after a manual fsck -- if not.
