Last was a shutdown while waiting for journalctl -b > dmesg51016b.txt to finish. I rand 12 passes with no errors of memtest86+ 4.20 on it last night. It has happened again today more than once. I remain hopeful of finding a correctable hardware cause of these shutdowns, assuming the cause is not a kernel support regression for the P6 III Tualitin. 3-This PC is also affected by bug 1141391 . 4-Today is the first day I started using mitigations=none instead of =auto.
