I've had a laptop here that has had some "issues" in the past (time
running double speed, XFree doesn't work, etc.)
Now I'm down to the last problem, USB doesn't work, which is a bit of a
pain for me :)
Anyway, below is the kernel log from 2.6.16-rc1-mm2 (contains the latest
acpi tree, which I thought might help out.) This log is when I modprobe
ehci-hcd. The interesting thing is the APIC error, and then the fact
that the interrupt screams off into oblivion. I can provide early
kernel boot info too, if you think that might help out.
Any thoughts?
I _think_ a real old 2.6 kernel used to work on this box, so I'll do a
bit of searching to see if I can find one and then try bisecting from
there...
Andi, I know you have been doing some apic rework for x86-64 (which this
processor is, but I'm still running it in 32bit mode.) Do you happen to
have any patch that I could test out?
thanks,
