If I do an S3 suspend, my machine resumes correctly (Thinkpad X40,

APIC_init_uniprocessor in the resume path improves things - I get edge
triggered interrupts, but anything flagged as level triggered doesn't
work. How can I get the ioapic fully initialised on resume?



Maybe you've found this bug?

I think you're right... I've applied the patch to 2.6.7, and I'm still running after a boot-suspend-resume cycle. Hopefully it isn't just a fluke :)

The original patch seems to have been logged at the time of 2.6.6. Was it just too late to make 2.6.7? Will it be fixed in 2.6.8?

Thanks.

Hamish.
