When waking my laptop from suspend, it behaves very strange - the CPU quickly gets hot and the battery drains insanely fast. Looking into powertop, there is a process called 'rtc_timer_do_work' that wakes up often and uses 10 Watts. Heres what powertop gives me:
Power est. Usage Events/s Category Description 10.44 W 51.0 ms/s 209.7 kWork rtc_timer_do_work
After a reboot that problem is gone, but I don't want to reboot after suspending, then suspend makes no sense at all.
Short description of my system:
- ASUS PRO62J
- i7 Q720
- 8G RAM
- Nvidia 240M
- Arch Linux w/ 3.7 linux-ck-nahelem Kernel
I've tried different kernels(default, ck, optimized ck from repository) and a multitude of kernel options(I've compiled the kernel like 20 times) but nothing has worked so far and when searching for the processes name nothing really helping pops up.
Is there any way to return this process to its normal state(a usage of several mWatts, not Watts)?
