With my 'own' kernel, AHCI has interrupt 315. I will try and make a more
monolithic kernel so I might be able to boot from a usb-flash device.

which didn't work. Hm, I am too stupid for that today...
Hmmm...
I will reboot from systemresucecd later today and post some results with
ahci-mode set, no nomsi. Just can't try patches that way.
Is sytemrescuecd using the same kernel? Otherwise, it will only add
more to the confusion.
almost. A heavily patched 2.6.24.2. That is why I don't sent a dmesg ... just
cat /proc/interrupts. I can send you lspci -vv and dmesg from systemrescuecd
if you want.
Aiee.... Can you please try 2.6.25-rc8 with both configurations? And
w/o systemrescuecd? Just seeing whether things mount properly or not is
good enough. There isn't much risk of losing data.
