PowerMac G5 quad-core, CPU A1 DIODE TEMP: 90.8 C (for example): How to handle? [more data]

[Mark Millard]

After a while the problematic quad-core G5 automatically shut down. b_intake.rpm was also always zero after a while. Before any patches I never saw zeros via sysctl dev.smu . The lines were from repeating the sysctl command about once a second and the zeros repeat second after second, with rare exceptions over the long count of seconds. I'll see about the updated patch.

I think that might be simply a timing issue.  I haven't seen any
problems testing on my dual G5.  How does the temperature look now?
Do you still have overheating problems?

I have an updated patch available at
https://reviews.freebsd.org/D1549 , which is what I'm testing on my
machine.
