JFFS2, 2.4.16, CVS-mtd -- mount, free memory, then hang

For a change of pace, and maybe fewer filesystem corruptions and oopses, I upgraded to 2.4.16 plus the mtd from today's cvs. I ran the patchin.sh and copied the cvs jffs2 code into the kernel tree. It compiled file, and boots. But once JFFS2 is finished complaining about empty blocks, etc and the filesystem is mounted readonly, 224k of memory is freed, then the machine hangs. Pressing <enter> produces newlines on the console, but init is never run. There's no complaints, though -- just nothing.

alt-sysrq-t shows that init is the current task.

call trace shows:
init
keventd
ksoftirq_CPU
kswapd
bdflush
kupdated
blkmtdd
mtdblockd
khubd

khubd appears to be the child of init, which seems strange.

Hmmm. What's its PC? Also what's the PC of these three:

Backtrace would be good too - I think 2.4.16 should be giving you that.

That's normal. All kernel threads are supposed to reparent themselves to init.
