PROBLEM: [2.6.7] irq 3: nobody cared!

hi kernel Volks,

2.6.7 runs into problems while setting up usb stuff and disables IRQ#3, (at least, for me) see kern.log:

using 2.6.6, it works, /proc/interrupts shows:

for more information regarding the system and its hardware, see attached lspci output. Both, 2.6.6 and 2.6.7 are using the same configuration, hope this helps.

bye,

I have that, only in IRQ#5
This didn't happen with linux-2.6.6 with the exact same configuration. The kernel isn't tainted yet, as it happens during bootup. I don't have anyting plugged in the USB ports, if that helps. --start-dmesg-output--
