I take that back.
Your sysrq-T woke up syslogd which did a synchronous write which poked
kjournald. You happened to catch it in mid-commit. So that's all normal
and sane.
Something is up with netdevice initialisation. My eth0 (e100) is in a
strange half-there state and won't come up. Reverting the post-2.5.70 e100
changes does not help. It's something which went into the tree today I
think.
