[-- Attachment #1 --] The machine will freeze hard a few seconds after powerd is started up by the rc script. With kern.smp.disabled=1, everything seems to work fine. This is with today's 6-STABLE/i386. I see that a fix for that sort of thing was only recently MFC'd, unfortunately I cannot say whether the problem was already there before it went in - the box is brand new. Various debugging information: sysctl -a | grep cpu: http://people.freebsd.org/~lofi/cpu_nosmp.txt http://people.freebsd.org/~lofi/cpu_smp.txt sysctl -a | grep acpi: http://people.freebsd.org/~lofi/acpi_nosmp.txt http://people.freebsd.org/~lofi/acpi_smp.txt dmesg -v (SMP) http://people.freebsd.org/~lofi/dmesg_smp.txt acpidump -dt: http://people.freebsd.org/~lofi/acpidump.txt Let me know if I can provide more information.
