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:

 	    CPU0       
   0:   10248130          XT-PIC  timer
   2:          0          XT-PIC  cascade

  10:          0          XT-PIC  uhci_hcd, Intel ICH5
  11:          0          XT-PIC  libata, uhci_hcd
  14:      15207          XT-PIC  ide0
 NMI:          0 
 ERR:          0

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,
    - michael
