Re: FYI: acpi | boot hangs when Laptop not connected to AC | NEC Versa FM320

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    Ok, the problem with boot hangs when AC is not connected to a laptop
    should now be fixed in the source tree.

    The problem turned out to be an early interrupt from ACPI caused ACPI
    to try to call tsleep() with a timeout in the SWI task code before
    the system clocks had been initialized, resulting in an infinite timeout.

    The original code misused SWI's terribly and the code FreeBSD-5 is using
    was not much better, so I rewrote the callback subsystem.
