Hi John,
I am not overclocking my CPU it was set to Auto in the Bios, I've
changed it to"Standard" now. I'm still getting the fatal DMA errors.
I tried cfq and deadline scheduling, I am able to set this on each of
my 4 harddrives. The options don't exist for the raid devices. I've
still seeing the problem with both of these settings. I've changed my
kernel to use cfq as the default now.
Last weekend I tried moving the hauppage cards around and from reading
the motherboard manual I was able to avoid them from sharing IRQs. The
following is the output of my /proc/interrupts:
CPU0
0: 124390 IO-APIC-edge timer
3: 92 IO-APIC-edge serial
8: 0 IO-APIC-edge rtc
9: 0 IO-APIC-level acpi
14: 24016 IO-APIC-edge ide0
15: 27952 IO-APIC-edge ide1
169: 45733 IO-APIC-level ide2, ide3
185: 3232259 IO-APIC-level sk98lin
193: 12890 IO-APIC-level ivtv0
201: 55107 IO-APIC-level ivtv1
209: 3337 IO-APIC-level uhci_hcd:usb1, uhci_hcd:usb2,
uhci_hcd:usb3, uhci_hcd:usb4, ehci_hcd:usb5
NMI: 1206
LOC: 124361
ERR: 0
MIS: 0
Note, ide2 and ide3 are shared because they are on the same pci ide
controller card.
Thanks,
-Todd
