I just built gcc on 2.4.19-rc3 + latest JFS and didn't have a problem.
I'll repeat it on 2.4.19-rc2-ac2, but there shouldn't be more than a
comsmetic difference in the JFS code. I haven't tried 2.5.27 yet.

It looks like tlck->mp was null in txUpdateMap, and hold_metapage was
called with the null pointer. I haven't seen this before, but I am
looking at the code to see if I can figure out how it may have
happened. I'm guessing that you have built the kernel without
CONFIG_JFS_DEBUG set. If I'm right, can you set this before you try to
stress JFS again. It may help find the problem earlier.
