Hi,
the laptop is still an Acer Travelmate TM291 (Centrino,
"hotpluggable" DVD/CDRW-Combo, bg2200 WLAN).
Using
set hw.pci.enable_io_modes="0"I get the laptop to get past the
PCI detection and get a Fatal trap 12 at or after USB detection.
I appended the last couple of lines from the console below.
Please advice, how I can get around this.
Regards,
Robert
