Hi, running latest illumos(ses), for quite a while I sometimes, not always, see a spurious warning on our T3500, always for CPU2:
------------------------Jun 23 15:23:16 xxxxx genunix: [ID 353554 kern.warning] WARNING:: Device /fw/cpu@2 failed to power up.
Jun 23 15:23:16 xxxxx cpudrv: [ID 774086 kern.warning] WARNING:: cpudrv_monitor: instance 1: can't raise CPU power level
------------------------ although already earlier, that CPU initialized correctly:Jun 23 15:23:15 xxxxx unix: [ID 518058 kern.notice] cpu2: microcode has been updated from version 0x10 to 0x1f
Jun 23 15:23:15 xxxxx unix: [ID 408514 kern.notice] initialized cpu module 'cpu.generic' on chip 0 core 2 strand 0
Jun 23 15:23:15 xxxxx unix: [ID 282553 kern.notice] initialized model-specific module 'cpu_ms.GenuineIntel' on chip 0 core 2 strand 0
Jun 23 15:23:15 xxxxx unix: [ID 950921 kern.notice] cpu2: x86 (chipid 0x0 GenuineIntel 206C2 family 6 model 44 step 2 clock 3467 MHz)
Jun 23 15:23:15 xxxxx unix: [ID 950921 kern.notice] cpu2: Intel(r) Xeon(r) CPU W3690 @ 3.47GHzJun 23 15:23:15 xxxxx unix: [ID 557947 kern.notice] cpu2 initialization complete - online
-------------------------
and psrinfo and ucodeadm show the CPU is in normal working state:
Status of virtual processor 2 as of: 06/23/2023 15:35:12
on-line since 06/23/2023 15:23:15.
The i386 processor operates at 3467 MHz,
and has an i387 compatible floating point processor.
CPU Microcode Version
....
2 0x1f
...
So could it be that this CPU really has some lurking problem, or
is it rather a kernel code glitch, maybe not correctly detecting that
it has indeed powered up the CPU, waiting not long enough ?
