Lenovo T61p fails to resume: screen remains black

Hey all,

I need my laptop to go to sleep and wake up.

Right now, I have FreeBSD 8.1 (PC-BSD), and suspend appears to work, but then resume doesn't.

I have acpi_ibm loading in /boot/loader.conf.

The following error is seen in the /var/log/messages

Anyway, I need sleep and resume. I looked at the USB errors, and I tried unloading usb first, as it says in the /etc/rc.suspend and enable usb in the /etc/rc.resume.

Code: 
# If a device driver has problems suspending, try unloading it before
# suspend and reloading it on resume.  Example:
kldunload usb

Doesn't matter if I have my wireless off or on.
 
Hello,

You are lucky - more than me. I have T61 and resume returns the black screen only. I can't even see the errors.

I would suggest to check the x86_64 version of PC-BSD (although I used plain FreeBSD) and check the sysctl variables for video blank etc. That may help.

If you find any solution please let me know. I will check at my end.

I couldn't even ssh in after resume.

I tried loading acpi_ibm, changing various hw.acpi settings.

Setting hw.acpi.reset_video to 1 had no effect.

If I had troubleshooting and debugging steps, I could probably fix this. I wonder if anyone has unit test for the code that ACPI sleep uses.

I wonder if setting hw.acpi.verbose will give me more data.
 
To excluded everything possibly failing, I disabled SMP and still I wasn't able to resume. I think that ACPI in FreeBSD is somehow broken.

NetBSD suspens/resumes fine for an instance.

Good luck- if you find something just share.

Pjoter.
