Hi,
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:

and acpidump:

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
but the screen just went black (black, but glowing, which is different
from ordinary suspend, where it gets completely dark)
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
working?
Thanks
