Description Hernan G Solari 2009-11-17 11:20:10 UTC
Laptop: Acer 5050-4697
CPU: 54bit AMD turion mobile
DSDT fixed with Marangoni fix (bug 8953. This was one of the test machines)

Running Debian squeeze (testing).

Problem: after suspending it resumes operation if suspended from console,
         but it gets frozen if it was suspended from X-session.

It happens with the debian kernel 2.6.30-2 recompiled allowing the reading of the DSDT.hex file (without this fix it gives one of the old errors, although it handles the battery well off the shelf).
There is no improvement with 2.6.30-rc7 (compiled as generic 64bit, in the past, compiling a k8 specific kernel resulted in unstable functioning)

However, after  "rmmod powernow-k8" it suspend/resume woirks from X

I can certainly live with this. Just reporting the problem and the dirty fix.

Hmm.  Perhaps it's the same thing I'm observing on one of my test boxes.

Can you do the following, please:

(1) Boot into runlevel 3 (no X)
(2) Suspend and resume
(3) Go into runlevel 5
(4) Log into X
(5) Suspend and resume

and check if the resume in (5) works.

Tests with 2.6.30-2 (I did not included powernow-k8 in the modules of 
2.6.32-rc7 I can do it if you want)

In this box X comes up. I haven't touched inittab, it is Debian's choice.

I can froze the machine in several ways....
a) boot as single user (init 1)    powernow-k8 is not running at this level
pm-suspend
resume comes to a dead machine
b) normal boot, suspend from X
resume comes to a dead machine
c) normal boot, <ctl><alt><F1>  login as root, pm-suspend
    resume comes to life in console mode..... BUT <alt><F7> frozens the 
machine

just in case it matters, the module acerhk (as distributed in source 
form by Debian) is loaded (former acer-acpi)

(Solved). The problem with following arragement:
eth0 no cable connnect
avahi-daemon tries to connect eth0 as indicated
in /etc/network/interfaces
and the machine frozens repeating dhcp calls

disabling the hotplug in /etc/network/interfaces ends the problem.

The problem sometines happens without resume or without running powernow-k8
