The brightness and volume keys also stop working (these don't send ACPI events, but seem to be on IRQ 9 anyway). The power button also generates nothing. Booting with noapic results in everything working. By the looks of it, the io-apic resume code rewrites all the registers in the io-apic. Is it possible that state is getting lost in the process? -- Matthew Garrett | mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by OSTG.
