Hi all,
The latest hint I received (thanks!) was to replace a failing hardware.
Before that, I updated the BIOS, which included a CPU microcode fix for
melddown/spectre and probably other thngs. Last time I had checked, the
vendor didn't have that fix yet.
Since this update, not CATERR happened... This Intel microcode + vendor
BIOS may have mitigated the problem, and postpones hardware
replacement...
