random insta-reboots on AMD Phenom II

2017-09-29 Thread Adam Borowski
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 1055
