During my attempt to upgrade from head -r360311 to -r363123 the old PowerMac has quit responding, without notification of why. The fans were going (expected even during normal operation for what I was doing) but the fan(s) did not wind up to full-noise/speed. Well, the machine finally did an automatic shutdown successfully, so the logs files were updated. What I found was: Jul 19 19:03:26 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.5 C) exceeds critical temperature (90.0 C); count=3D1 Jul 19 19:03:28 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.2 C) exceeds critical temperature (90.0 C); count=3D2 Jul 19 19:08:41 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.3 C) exceeds critical temperature (90.0 C); count=3D1 Jul 19 19:08:43 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.3 C) exceeds critical temperature (90.0 C); count=3D2 Jul 19 19:08:45 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.3 C) exceeds critical temperature (90.0 C); count=3D3 Jul 19 19:08:49 FBSDG5L2 syslogd: last message repeated 1 times Jul 19 19:08:51 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.2 C) exceeds critical temperature (90.0 C); count=3D4 Jul 19 19:12:11 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.2 C) exceeds critical temperature (90.0 C); count=3D1 Jul 19 19:14:06 FBSDG5L2 syslogd: last message repeated 1 times Jul 19 19:14:12 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.7 C) exceeds critical temperature (90.0 C); count=3D1 Jul 19 19:14:14 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.7 C) exceeds critical temperature (90.0 C); count=3D2 Jul 19 19:14:16 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 91.0 C) exceeds critical temperature (90.0 C); count=3D3 Jul 19 19:14:18 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.7 C) exceeds critical temperature (90.0 C); count=3D4 Jul 19 19:14:28 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.5 C) exceeds critical temperature (90.0 C); count=3D2 Jul 19 19:14:30 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.8 C) exceeds critical temperature (90.0 C); count=3D3 Jul 19 19:14:32 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.8 C) exceeds critical temperature (90.0 C); count=3D4 Jul 19 19:14:34 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.7 C) exceeds critical temperature (90.0 C); count=3D5 Jul 19 19:14:36 FBSDG5L2 kernel: WARNING: Current temperature (CPU B1 = DIODE TEMP: 90.3 C) exceeds critical temperature (90.0 C); count=3D6 Jul 19 19:14:36 FBSDG5L2 kernel: WARNING: CPU B1 DIODE TEMP temperature = exceeded critical temperature 6 times in a row; shutting down!

I'm now testing the media in the 12 GiByte 2-socket/2-cores-each (2 pumps) as a cross check on HW vs. SW. (Likely HW.) I've started up poudriere again. The 16 GiByte PowerMac failed in somewhat under 30 min of poudriere bulk activity (with a load average of more than 4 much of the time). . . . On the 12 GiByte, it has been 105 min+ with 0 temperature notices. So another old single-pump "Quad" may have bit the dust but the dual-pump one is still going. The 12 GiByte PowerMac has bad memory slot(s) and so cannot have 16 GiBytes of usable RAM. (I no longer remember the details.) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
