i'm trying FreeBSD 7.1 BETA2 in amd64 and i'm having issues with interrupt storms. The machine works without problems as long as i don't stress much the HD. If i have high IO load after a few hours the system starts to have interrupt storms and never again recovers from them until i restart.My SATA card is: [EMAIL PROTECTED]:0:18:0: class=0x01018f card=0x73271462 chip=0x43801002 rev=0x00 hdr=0x00 vendor = 'ATI Technologies Inc' device = 'IXP SB600 Serial ATA Controller' class = mass storage subclass = ATA The MotherBoard is MSI K9AG Neo 2[1] and the kernel is GENERIC without USB and firewire support. After digging a bit in the source i've find that linux people have a quirk for this chipset and i've been unable to find in our code a similar quirk. You can find the quirk here: http://fxr.watson.org/fxr/source/drivers/pci/quirks.c?v=linux-2.6#L870 I don't know exactly what does it do, neither i do know if it have anything to know with my interrupt issues, but could someone who knows a bit better tell me if that could fix the issue or if we need that quirk for other purposes?
It seems this quirk only changes PCIR_PROGIF and PCIR_SUBCLASS registers to PCIP_STORAGE_SATA_AHCI_1_0 and PCIS_STORAGE_SATA values. I don't know which magic these changes should do, but I think they aren't needed. Your controller should work in AHCI mode without this quirk. -- WBR, Andrey V.
