Re: USB burps with irq XX: nobody cared. (2.5.70)

[David Brownell]

Looks like a stream of IRQs getting delivered before
the chip was initialized ... interrupts that shouldn't
have been arriving.  Do you have funky BIOS settings?

Does this happen if you don't use ACPI?  I've had
reports of folk using NForce2 boards that needed
to use "acpi=off", since ACPI didn't initialize
the interrupts correctly.  Yours seems to be at
least partially correct.

USB burps with irq XX: nobody cared. (2.5.70)

[David Ford]

This is one of those systems that has some 150K of dmesg on boot due to 
that pesky USB barfing - IRQ XX nobody cared!.

Due to it's size I haven't included it here.  Here's a link to it 
however - http://blue-labs.org/~david/dmesg.out.2.5.70.bz2

(There are a lot of unknown devices in lspci output, if an interested 
party wants, I'll provide as much detail as I can.)
