SubjectRe: [ACPI] [PATCH][RFC] fix ACPI IRQ routing after S3 suspend

Stefan -

Can you please attach 'cat /proc/interrupts' from a system that has all
possible drivers for your hardware loaded. From before suspend.

Also - did suspend/resume for the ipw2100 ever work under any kernel
version?

Thanks.
Nathan
