on my Toshiba M40 I had lots of trouble with netcard, Marvel Yukon 2.
Problem ended up being that ohci1394 crashes, disabling irq11 at all.
irq11 is used by Yukon. so no net. but I oversaw it, thinking it was
benign.
It could even be a nasty interference among the many device
sharing irq11:

so, on kernel-2.6.14-1.1644_FC4, Pentium M 2GHz, 1GB RAM, I get:

booting with:
#alias ieee1394-controller ohci1394
in /etc/modprobe.conf, it's magically all ok. no kernel msg reporting
problems.
but, why the hell ohci on irq6 is disturbing devices on irq11 ??
