I have recently installed freebsd-9.1RC on my thinkpad t420i laptop and
I have run into some problems regarding acpi suspend/resume.
When I run
# acpiconf -s 3
Computer seem to suspend correctly, but when I wake it up, laptop seems
to resume correctly except the screen stays dark.
I have made dmesg dump after boot with verbose booting:
I tried to boot without acpi, but the system did not boot at all.
I have also tried suspend with
# sysctl debug.acpi.suspend_bounce=1
and this is a resulting dmesg during suspend:
I haven't found any problem connected to LCD/screen or something like
that. Do you have any idea what to do in order to make suspend/resume
