here's the latest version of the voluntary-preempt patch: http://redhat.com/~mingo/voluntary-preempt/voluntary-pr[...] this patch is mainly a stabilization effort. I dropped the irq-threads code added in -M5 and rewrote it from scratch based on -L2 - it is simpler and should be more robust. The same /proc/irq/* configuration switches are still present, but i added the following additional rule: if _any_ handler of a given IRQ is marked as non-threaded then all handlers will be executed non-threaded as well. E.g. if you have the following handlers on IRQ 10: 10: 11584 IO-APIC-level eth0, eth1, eth2 and you change /proc/irq/16/eth1/threaded from 1 to 0 then the eth0 and eth2 handlers will be executed non-threaded as well. (This rule only enforces what the hardware enforces anyway, none of the previous patches allowed true separation of these handlers.) i also changed the IO-APIC level-triggered code to be robust when redirection is done. The noapic workaround should not be necessary anymore. the keyboard lockups are now hopefully all gone too - i've tested IO-APIC and non-IO-APIC setups as well and NumLock/ScrollLock works fine in all sorts of workloads. Let me know if you still have any problems.
