Hi,

I have a 6.3 (RELENG_6 a bit past 6.3 actually) system which hangs when I try and reboot (or shutdown). It has a Supermicro C2SBA+, 2ware 9650SE and Core2Duo CPU.

It shuts down as normal except after printing the uptime it hangs solid. Numlock does nothing (during the shutdown process & disk sync it toggles OK). The disks are synced OK (comes up clean when I press the reset switch)

Waiting (max 60 seconds) for system process 'vnlru' to stop...done Waiting (max 60 seconds) for system process 'bufdaemon' to stop...done Waiting (max 60 seconds) for system process 'syncer' to stop... Syncing disks, vnodes remaining...6 5 2 3 0 1 0 0 0 done All buffers ynced. Swap device da0s1b removed. Uptime: 1m52s <hang>

I have tried setting hw.acpi.disable_on_reboot and hw.acpi.handle_reboot to no effect.

I have attached a verbose dmesg.
