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? -- Matthew Garrett | mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
