https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209202 --- Comment #5 from Mark Millard <markmi@dsl-only.net> --- (In reply to Mark Millard from comment #4) Such timing. . . Looks like the single pump cooling system started dying as of a couple of d= ays ago (May 25). Interesting oddities compared to my other exeriences: A) The problem is intermittent. B) While it is working normally the CPU diodes for CPU's B0 and B1 are the cooler 2 of 4 according to sysctl results but it is B0 and/or B1 that start getting readings in the 90+ degC range when it fails. C) I've had complete buildworld's with no sign of the problem. Other times = it shuts down fairly soon after starting that or other much smaller builds. (6= or more 90degC+ readings in a row initiates shutdown.) Its boot drive is at -r298990 (as of May 5) and it was off from May 6 throu= gh May 21 so it is not a great test of if the -r298990 update had a software change that might be contributing. --=20 You are receiving this mail because: You are the assignee for the bug.=
