Subject: ahci_host_intr BUG

Background: I have a yet-unidentified problem with 2 HDD-s that are very 
slow and often time out. They are connected to Intel ICH5R SATA 
controller. I tried with both ata_piix and ahci drivers. I 2.6.15 era 
driver, any such SATA error hung up the disk. In 2.6.17 (Debian 
2.6.17-2-686 kernel, package version 2.6.17-7) the errors are handled 
much better, woprk is resumed after timeout. ata_piix just logs the 
messages about timeout, drive being { Busy} and then reset and continue. 
AHCI driver on the other hand logs this on every error but then 
continues fine (albeit slowly):
