Regression: Wake up from suspend stopped working

[mogliii]

Toshiba NB550D netbook, AMD C-50 APU, SSD. Kubuntu 11.10

Yesterday evening I applied new patches, including new kernel version. Before update, suspend to ram and wakeup worked ~20 times consecutively.

With new kernel version 3.0.0-13.22 wakeup does not work anymore. HD activity LED does not blink at all when waking up.

The previous version (presumably 3.0.0-13.21) was the first version since buying this netbook in July of this year which allowed reliable wake-up from suspend to ram. Kernel versions before showed similar symptoms (No disk activity on resume) as the one reported now.

So for my hardware the new version is a clear regression.

<speculation>
This change might have influence, as the netbook has combined wireless/Bluetooth module

Added information shows "Linux 3.0.0-12-generic x86_64" as I booted into older version using GRUB to try if the same happens. So the bug is, as stated in the description, against 3.0.0-13.

Using 3.0.0-12 does not fix the problem. The working version must have been overwritten on update as it is also from the 3.0.0-13 family.

Somehow was filed under xorg. Should, of course, be Project linux
