Actually, I got this messages on the screen during runtime:
Message from syslogd@foo at Thu Jul 7 13:06:35 2005 ...
foo kernel: Assertion failure in journal_write_metadata_buffer() at journal.c:406: "buffer_jdirty(jh2bh(jh_in))"
The machine would then hang and I have to do hard reboot
I did fsck on the harddisk once and fsck said it is fine.
Maybe there are hardware problem.
So, I want some more hints from the kernel.
Thanks,

If you have to ask this question, even if you manage to recompile the kernel
with additional debug stuff, you're not likely to make much sense out of the
output.
If you suspect filesystem corruption, the easiest thing to do is to create a
dummy zero-length file "/forcefsck", then reboot.
Then, during boot, all of your filesystems will get checked.
