Got a kernel panic at system shutdown, after initscripts said "Unmounting
This is with the released ext3 kernel RPMs, i586 version, with the root
partition on ext3:
Assertion failure in journal_flush() at journal.c: line 819
"journal->j_head == journal->j_fail"
Unable to handle kernel NULL pointer dereference at virtual address
current->tss.cr3 = 021c9000, %cr3 = 021c9000
*pde = 0000000
I shut down the system immediately after extreme load (this was a poor
PII-200, and I just installed glibc, glibc-devel, and openssh errata).
After the system rebooted, I verified that the installed packages were OK.
It's a known problem with remounting a filesystem readonly, and is fixed in more
recent versions. There is no risk of data corruption from it.
