irq 19: nobody cared

[Chris Li]

Hi,

I run into this irq nobody care problem on a dell vostro 200 machine.
I test the latest git tree. The problem is there as well.
I also update the BIOS to the latest version. Doesn't help either.

It seem the IRQ in question is shared between UHCI and SATA controller.
So I am not sure it is a SATA problem or a USB problem.

 =======================

I attached the kernel config file, dmesg and /proc/interrupts.

Any suggestions? I am willing to try fancy patches.

Thanks

Chris
