This could be similar to thinkpads, see my response to Honest Qiao's
X201...
Here's the short version:
In single user, set hw.pci.do_power_resume=0 and
hw.pci.do_power_suspend=0
Try suspend bounce (and if successful suspend) with suspend beep
sysctl on.
If that fails (either bounce or full suspend) try just
hw.pci.do_power_resume=1
repeat test (bounce then full suspend)
If that fails (either bounc or full suspend) try just
hw.pci.do_power_suspend=1
repeat test (bounce then full suspend)
Thanks Matt for your suggestions.
I'll use suspend for hw.pci.do_power_suspend and resume for
hw.pci.do_power_resume.
The tests were made in single user with an stripped kernel (I can
show a kldload -v if needed); no firewire, sdhci, mmc, if_ath, if_em, etc .
The short story is:
- without bounce and any combination of suspend and resume, the
machine beeps forever when resuming from a full suspend
- with bounce, with any combination of s/r but suspend=1 and
resume=0 the machine stays alive without video (it gets full
illuminated). With bounce and suspend=1 and resume=0 the machine freezes
hard (I heard no beep because of bounce=1)
With bounce (when it doesn't freeze) I can do ls -laR /, grep's and
I see the HD spining, so it stays alive with the bounce.
I tried the same tests (8) with acpi_video loaded and the results
were the same. Because it seems to work with bounce and because it beeps
when returning from a full suspend I would say that the problem is in
the resume code path.
I could also do all the tests with acpi_fujitsu but it only gives the
possibility to use the acpi controlled buttons on the notebook. The
first time I tried to suspend/resume I was using acpi_fujitsu and the
machine did not resume.
Thanks for your help.
