Ah found it an earlier thread which has 17 for > the !ACPI case. So try it with ACPI disabled and the above tunable. Also, > it should work with both ACPI and APIC disabled. I don't see how this tunable (irq 18) can work if APIC is disabled, shouldn't this tunable lesser than 16 in that case? -- Bruno Ducrot -- Which is worse: ignorance or apathy? -- Don't know. Don't care.
