OK, got some good news at the moment. I've dropped some boot options:
'intel_idle.max_cstate=0 processor.max_cstate=0 idle=mwait' and now the system
seems to work OK. No delays, no issues, works as expected.
When idle=mwait option was set, I saw some error in dmesg:
Malformed option 'idle'
Checked the kernel code in arch/x86/kernel/process.c and seems mwait was
dropped, only pool, nomwait and halt is possible.
Got no idea why mwait was dropped, would have been nice to know :)
Can idle option or the other cstate option create so many issues? I don't think
the idle option has anything to do with the issue, as it was malformed, but the
other 2 I'm sure was doing the nasty :)
