Hello,
I have a some problem of APM with 5.0-current.
In the case which I type
# shutdown -p now
the system does halt or reboot( this seems to be somewhat unstable),
and never off the power of the PC.
To find the problem, I produced the crash dump and analyzed it by gdb.
The result was :

The value of the first arg of apm_power_off 0x4008 is identical to
howto = ( RB_POWEROFF | RB_HALT ) (see /usr/src/sys/sys/reboot.h),
which should be the value of the second arg of apm_power_off function.
I guess something goes wrong. I couldn't, however, find any solution to
this. Added to this, I must report that 4.2-stable running on
the same PC can power off without any kind of problems.
Does someone have same problem? Is it proper to me? Does someone have
a suggestion?
