Hi,
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.
2.6.25-rc8 is a 'no change'. AHCI+pci=nomsi boots, AHCI without hangs.
with AHCI I also get this:
[ 0.363828] ------------[ cut here ]------------
[ 0.363828] WARNING: at drivers/ata/ahci.c:645

Heh.. that's AHCI_EN not getting set. Peer, any ideas? The driver set
AHCI_EN in the HOST_CTL register but on reading back it's still clear.
Possibly the hardware is not idle? I wonder if the BIOS is doing
anything with the IDE interface. _Probably_ not, but that is certainly
a situation where switching to AHCI can be a problem for certain AHCI chips.
