If I do an S3 suspend, my machine resumes correctly (Thinkpad X40,
acpi_sleep=s3_bios passed on the command line). If I have the ioapic
enabled, however, I get no interrupts after resume. Hacking in a call to
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?


I have an identical problem with an r50p. But I'm running PIC... (Because the r50p doesn't seem to do APIC). Not sure if it's identical, but after resuming, I get maybe 10 seconds of sound, OR 30 odd minutes of networking (I know... Sounds strange)... Then neither...
