Yes, Its getting further... I can now mount /dev/sda1 to /mnt/flash (or
wathever) when I have the ACPI=off.

I tryed to make the ACPI=noirq. Then the I rebooted, and the computer
hang, right after the graphical boot said: setting hostname (or
something.. I have norwegian text on it) Also the my usb mouse dident
work during this startup (it normaly does work).

I then had to edit the kernel parameter from grub to make it boot.

I also has a Apacer handy steno 1.1 256mb disk, i was also able to make
this work with the ACPI=off. The only thing here is that the Apacer
stick is /dev/sda, even if only this stick is in the usb port.

Why does 1 of them use /dev/sda, when the other comes in as /dev/sda1 ?

I've added both of them to /etc/fstab as:
/dev/sda		/mnt/flash		vfat noauto,user,rw 0 0
/dev/sda1		/mnt/flash2		vfat noauto,user,rw 0 0

Is this the correct way to do it? and if I set it to auto instead of
noauto, will it then automaticly mount when I insert it?

Also, how can I disable the graphical boot to see wats going on when the
hangs during the boot?

James was also earlyer talking about maby making a bugzilla entry about
this.. Is this problem something to add to bugzilla, and if so.. how?


Many thanx for all the good help James!!
