I've been using JFS for several years now, and the only time it has ever 
given me a fault is when I have a machine crash, and then crash again on 
boot.  It trashes whatever it was writing to the second time, invariably 
/var/lib/init.d, which then hoses subsequent attempts at booting.  The 
only way to fix it is to forcefully fsck from single user mode.

That further seems to indicate it has nothing to do with your 
filesystem, but something lower level.
