Heyas folks --
Now that the power management framework is merged and things have settled
down a bit, now is a great time for you to provide us feedback on results
of your suspend/resume tests.
It's really quite simple. Ensure you have a -current kernel from at least
now or later, and a machine that supports suspend to RAM. Both uni- and
multiprocessor kernels should work.
Some notes before you get started:
* Do your initial tests in single-user mode, to save potential fscking.
* If you get an immediate reboot on wakeup (as is the case on most Dell
laptops), set the following sysctl:
# sysctl -w machdep.acpi_vbios_reset=0
* If you do not have video on resume, please install sysutils/vbetool
from pkgsrc. The following command on resume should bring things back:
# vbetool post
This can either be typed blindly, or scripted.
* If you can't suspend because a loaded driver doesn't support the PMF,
boot into userconf with 'boot -c' and disable those drivers if
possible. Even better, send-pr with patches to make them properly
capture and restore state.
Alright, now for the moment of truth. Boot single user and execute the
# sysctl -w machdep.sleep_state=3
