Hi
I have given output of cat /proc/interrupts

And by can any one tell me whether cmpci and usb-uhci
will cause any problem. Actually my pc hangs if i paly any sound related applications.

14: 19108 XT-PIC ide0
15: 2235 XT-PIC ide1

They should not cause a conflict if they use different memory locations. That is the whole point of bus mastering: to allow different cards on the PCI bus to share interrupts. But they cannot be mapped to the same memory locations. Post a

lspci -vv

and check.

Thanks
below i have given a part lspci -vv

Hmm. Diffent memory I/O locations. No conflict there.

Do you have Plug-N-Play (PnP) turned OFF in the BIOS of your mother board?
