We only recently started testing JFS for use as a root filesystem and we
have a few fixes that went into the 0.3.2 and 0.3.3 drops that you will
probably need. I would advise you try again with the JFS 0.3.3 code.
That said, I'll warn you that we haven't tested this on a 2.2 kernel,
but if you have gotten it to boot off JFS once, there's a decent chance
that it will work with the latest JFS code.
Thanks for reporting this and please let me know if you have any more
problems with it.
