patching file drivers/ata/ahci.c
Hunk #1 succeeded at 397 (offset -5 lines).
Hunk #2 succeeded at 1819 (offset -45 lines).

built&booted, same results as allways. With non-raid setting, IDENTIFY error
on cold boot and sofreset error on reboot:
(with patch, without nosmi):

btw, with 2.6.24.3, without nosmi and my own config it stays at 315. So
non-raid and ahci both get the same interrupt, and the same error (ahci
always gives the IDENTIFY error, on cold boots and reboots). But non-raid
finds the harddisks at the end, ahci does not.
