No, setting the parallel port to ECP (SPP detected) in the bios, the
same problems remain.
However, when resettting to EPP mode, I noticed I used EPP 1.7. When I
switched to EPP 1.9, the problems also remained, but the system seemed
'harder to crash'.
It crashed though, and here are a few of the messages that were
apparently recorded to syslog (EPP 1.7 and ECP didn't record anything):
