When attempting to reboot the system freezes at "stopping other CPUs"
and has to be hard-reset with either the power button or the RESET
switch. The problem is easily reproduced - typing "reboot" produces
it :-)
I'm wondering if that ACPI warning in the boot sequence is involved in
this, and if so, if there is a recommended workaround?
Here's the "dmesg" from the subject system:
Hi,
I have the same chipset, but dont see the reboot problem on
RELENG_7 from Jan 7th. (via "shutdown -r now") Have you checked for
BIOS updates ?

Hi,
I don't get the numbers of CPUs -- AFAIK Core i7 has 4 cores with 2
logical CPUs per core (hyper-threading?) and that makes 8 logical CPUs.
Above I see 8 cores per package (!) _but_ 8 x 2 = 16 while only 8 CPUs
are detected and started. Could someone explain pls ?
Cheers,
M.
