acpi related, but on freebsd 4.11 (cvsupped and built on 24 march).
i've compiled with device acpica in the kernel, but i get sporadic page faults as attached.
i do know that acpica is experimental and that LINT does warn of kernel
panics and machine hangs. however i was wondering if anyone has got this
working succesfully on any machine.
The problem is that the taskqueue_swi in 4.x doesn't have a thread context that can be slept on via tsleep(). The fix would be to create a kthread in which to run the ACPI tasks. 4.x already has one such kthread for the taskqueue_thread taskqueue that you could use as a reference if you wish to do this yourself.
