Manoj Iyer - Jan. 14, 2011, 8:17 p.m.
Set acpi_skip_timer_override to force ignoring BIOS
IRQ0 pin2 override. This fixes resume from suspend on
AMD based ThinkPad Edge 11,13,14 and 15.

Please note that with this patch applied, you will see
a warning message from the kernel, this is printed in acpi/boot.c
before it sets acpi_skip_timer_override=1;

Is there a difference to the last patch you took back yourself?
Manoj Iyer - Jan. 14, 2011, 8:39 p.m.
No there is not, I talked to Tim and he suggest I re-submit because he
had deleted it from the queue.
