Hi! I'm afraid I see random instant reboots on current -rc, approximately once per day, only under CPU load. There's nothing on serial/etc -- just an immediate reboot. 4.13 works perfectly; last kernel I've tried is v4.14-rc2-165-g770b782f555d. gcc 7.2.0-7 (Debian).
CPU is AMD Phenom II X6 1055T (family 10h). Sometimes it dies within a few minutes of load, sometimes all is fine for a couple of days. This randomness makes bisecting not really an option. Any hints how to debug this?
