Hi,
After a few tests with the latest kernel (3.14.0-031400rc6-generic
#201403100035 SMP Mon Mar 10 04:36:54 UTC 2014 x86_64 x86_64 x86_64
GNU/Linux) it is far better, but not enough!
Basically, the resume work, but a kernel thread (kworker) is eating 100% of 1
CPU core.
Time to time, it stop working for, something like less than 1s. I was able to
launch htop under an X terminal, to see that.
The time this worker thread work, is not constant, something between 10s to
2min. During this time X freeze completely, and all others programs with it.
During the clean reboot ('sudo reboot" in my X terminal), it happend too. The
events are still monitored during that time. Even if the screen was frozen, I
could type on the keybord or move the mouse. Just have to wait the worker
thread to let others programs to work a little.
I tried to look at the logs, but I didn't found any evidence which may permit
me to better know what was going on.
The only error in /var/log/pm-suspend.log is:
Running hook /usr/lib/pm-utils/sleep.d/60_wpa_supplicant resume suspend:
Failed to connect to non-global ctrl_ifname: (null) error: No such file or
directory
/usr/lib/pm-utils/sleep.d/60_wpa_supplicant resume suspend: success.
I don't know if it is related.
You may notice that I have an another bug on this laptop. I can't use
the proprietary WiFi driver (which is installed by default). This driver
(firmware ? crashed with an "invalid instruction" error. It seems to not
be compatible with an "AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55"
(on GNU/Linux only, I tried Win8.1 on this laptop, the driver worked
fine). That is why, I only use the ethernet connexion,with the FOSS
driver. Again, I don't know if this information can help too.
I will retry with the stock kernel, maybe it's the same, I just didn't
wait 2min before performing a halt/boot. There is no hardware reset on
laptops :-(
Thank you.
