Bug#1036900: Things I tried
After googling, I tried a few things:
Memory has correct timing, frequencies and voltage (no improvement)
kernel parameters => no improvement
- idle=nomwait
- processor.max_cstate=5
- rcu_nocbs=0-11
Undervolting / Overclocking => seems to make the system a bit more
stable
- Reducing PPT to 45W
- PBS Curve all cores: -10
- Boost limit: -300 (ending around 4Ghz)
Deactivate SMT => no improvement
Deactivate selective CPUs (Error always showed on CPU5) => no
improvement
Deactivating tx, sg, tso offloading => no improvement
Overall it seems the system crashes when doing load changes, e.g. like
compiling. It then takes SATA, network, etc. down, leading to an
unusable system.
