Hello,
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:
atapci0@pci0:0:18:0: 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?
Regards.
Thanks in advance.
