Interrupts still doesn't work?
Try cat /proc/interrupts or /var/log/messages to see if it get interrupt.

You can use 2.6.19 later kernel and enable HT_IRQ in it. --- Eric

it out, and I didn't have chance to test it.
Hey, 2.6.19.1 actually boots (better than 2.6.19)! 2.6.19.1 with HT_IRQ turned on yields:
sh-3.1# modprobe ib_ipath PCI: No IRQ known for interrupt pin C of device 0000:40:01.0. Probably buggy MP table. mtrr: type mismatch for fd500000,100000 old: write-back new: write-combining ib_ipath 0000:40:01.0: mtrr_add() WC for PIO bufs failed (-22) ib_ipath 0000:40:01.0: infinipath0: Write combining not enabled (err 22): performance may be poor
Note that HT_IRQ removes the complaint (formerly right before the mtrr complaints):
ipath_core 0000:40:01.0: infinipath0: irq is 0, BIOS error? Interrupts won't work
Further fun stuff to try? I am your board monkey.

Seems to have one: sh-3.1# cat /proc/interrupts CPU0 CPU1 0: 4906 0 IO-APIC-edge timer 1: 2 0 IO-APIC-edge i8042 2: 0 0 XT-PIC-XT cascade 4: 90 0 IO-APIC-edge serial 8: 0 0 IO-APIC-edge rtc 12: 4 0 IO-APIC-edge i8042 19: 71 0 IO-APIC-fasteoi ohci_hcd:usb1, ohci_hcd:usb2 27: 6 0 IO-APIC-fasteoi eth0 1279: 62 0 PCI-HT-edge ib_ipath NMI: 72 31 LOC: 4826 4819 ERR: 0
I have to cart it to the rack to actually try the IB, and since I'm having to hot-swap from the Iwill bios every time I flash (any clue why flashrom -w when booting under LB fails immediately with "ERASE FAILED" and trashes the image in flash?) I was hoping we could get the MTRR thing licked too before I actually do a 'does it really work and how fast' test. The MTRR complaints are not normal and don't happen under the Iwill bios.
Full bootlog including /proc/interrupts, iomem, mtrr, ioports attached.
