It locked up again, but the important part is not in the mail or the wiki: 
clear the error log before :/ And even worse, the C8000 does not seem to 
support "ser clearpim". You can see the firmware commands of a C8000 here: 
https://parisc.wiki.kernel.org/index.php/BMC.

Fun fact: when doing a command in firmware that prints a lot of stuff, like 
"se", and then switching back to the normal system console via ESC-) seems not 
to stop the firmware from printing more of it's stuff, so you get junk on the 
serial line until the firmware is eventually finished. Is there a way to 
switch the C8000 firmware to more than 9600 baud?

Sorry for the bad mood, but if that is what you first find after wakeup…
