It happened again: This time with 2.6.38.4 after 13 days uptime.
In fact it was "13 days after last boot", since this machine is
hibernated quite often. I waited only two minutes before I run
'reboot' as root.

See http://pastebin.com/raw.php?i=XnXXfC40 (It seems to me SYSRQ+l
did not work at all? And does also not work on 2.6.38.5?)
see http://pastebin.com/raw.php?i=Zuv0VnUP for 'top/iotop'

I had no access to my mails and forgot to run 'ps xal'. :-(

Definitely not fixed in 2.6.38.4.
