Re: ACPI and Linksys 10/100 PC Card (ed1)

Hi Matt,

I've tried the 'boot -a -v' options and it doesn't ask for the root 
partition or anything else to mount; so I'm assuming that the machine 
falls over before actually reaching that point.

I've played around with the options suggested by YONETANI Tomokazu, and 
the machine seems to boot when I use either:
debug.acpi.disabled="bus"
or
debug.acpi.disabled="children"

This enables me to boot the machine, but I have problems with console 
blanking and the screensaver under X doesn't seem to want to activate 
automatically either.

I am not sure how to further aproach the debugging process.  The "boot 
-v -a" option did not give any more interresting information, it still 
only gets to the point where it assigns the CDRW/DVDrom device and then 
the machine hangs there.

Any ideas?

Kind regards,

Henry
