Hi,
I recently got my new ThinkPad X31, which is the first laptop of my own.
Having
hw.pci.allow_unsupported_io_range=3D"1"
being set and ACPI loaded, FreeBSD 5.2-CURRENT runs mostly happily.
However, I am having problems about suspension (S3) and hibernation (S4).
After setting
hw.acpi.sleep_button_state=3DS3
hw.acpi.lid_switch_state=3DS3
hw.acpi.standby_state=3DS3
hw.acpi.suspend_state=3DS4
Fn-F4 seems to be working, but the LCD backlight does not turn off (it just
blanks out). After resuming from S3, USB and firewire do not work. I tried
to kill usbd and unload usb.ko before going to S3, but kldunload keeps
telling me
kldunload: can't unload file: Device not configured
and refuses to unload it. If I have X running when entering S3, X hangs
even I switched to console before sleeping. I tried
options SC_NO_SUSPEND_VTYSWITCH
but in vain.
What is of more concern is that I can't have my hibernation work. I have
created a hibernation partition using phdisk, but nothing happens when I
press Fn-F12 under FreeBSD. If I use=20
acpiconf -s 4
to force it hibernate, it does look as if it is entering hibernation.
The Moon LED flashes and then the power turns off in a few seconds.
But when I press the power button and choose to boot FreeBSD in
BootEasy (Is it normal that the boot manager still runs when waking
up from hibernation? Windows seems to work this way...), it looks perfectly
as if it is a normal boot-up, which means that it complains about not-
properly-unmounted / and begins to do background fsck, and not like a
wake-up at all. Am I missing some important points to do?
Sincerely,
Leland Wang
