My first Micro-Server-Build is frustrating....
Every few days (or rather nights) if I'm not at place, it freezes up.
The used asrock j3455-itx seems to have some critical problems with Ubuntu 18.04.
My first guess was Intel C-State... ...But even disabled in bios the system freezes
random. (And no, there is nothing in logfiles...)
Yesterday i've installed the HWE-Kernel 5.3.0-59 and hope it'll fix the freezes as it contains
new i915-drivers for cpu/gpu...
...so lets have some tea or beer and wait for the next random freeze...
If it'll come to another freeze I'll try:
- Replace RAM CN-Memory with some of Hynix
- GRUB-Command "intel.idle.max_cstate=1" (Think it would not help as C-States are disabled in Bios...)
