LOR with latest ACPI code...

[gnn at freebsd.org]

Hi,

When trying to suspend (zzz) my Fujitsu P7010D Lifebook (dmesg
attached) I get this:

fwohci0: fwohci_pci_suspend

acpi: suspend request ignored (not ready yet)

Although the machine suspends and resumes, the display is dead.  I can
still ssh into it, but I cannot revive the display:

shonan ? sudo sysctl hw.acpi.video.
hw.acpi.video.crt0.active: 0
hw.acpi.video.lcd0.active: 0
hw.acpi.video.tv0.active: 0
hw.acpi.video.ext0.active: 0
shonan ? sudo sysctl hw.acpi.video.lcd0.active=1
hw.acpi.video.lcd0.active: 0 -> 0

I'm willing to test patches etc. as this is very close to being a very
nice little, workable, FreeBSD CURRENT box.

Thanks,
George
