Martin,
After our discussion regarding the IRQ being assigned to for my USB to be the
same as the sound card, I tried this patch.
Kernel version 99pre3 + pci patch
Previously we got the correct IRQ assigned to the USB controller with Pre7 by
adding pci-irqmask=0xff00
Now what happens is lspci shows 0 with and without this option on boot.
However when usb-uhci is loaded, it detects IRQ 6, without the pci= option, and
irq 9 with it.
uhci refuses to load in both cases, compaining of IRQ not set.
However the problem with the Oops still happens when usb-uhci is loaded, as
before.
WITHOUT pci=irqmask=0xff00
PCI:enabling device 00:01:2 (0000+0001)
IRQ for 00:01.2(3) via 00:01.2 -> PIRQ 3, mask 02F8
excl 0000 -> newirq =6 => assigning IRQ 6 ... OK
WITH pci=irqmask=0xff00
Same as above but IRQ=9
As said, uhci refuses to load in both cases, and usb-uhci causes a large oops,
killing the system.
I have not managed to get USB working in 2.3.99pre3, pre7, pre8 or pre9. Also
tried 2.2.15pre17, with no joy.
How can I start to get to the bottom of this ???
lspci & dmesg attached for both cases....
Thanks,
Alan
