I have just installed 6.9-stable/amd64 on a new-to-me (used) Lenovo
Thinkpad T580 (dmesg below). This was a from-scratch install on a
new-from-the-factory SSD (via booting the 6.9/amd64 bsd.rd from a usb
stick).
During the installation (both in the bsd.rd install script and previously
when I dropped into the bsd.rd shell to set up softraid-crypto) the machine
acted incredibly slow, and there was a several-second delay in echoing
typed characters. I suspected that it was some device producing spurious
interrupts, and just let the install run overnight until it finally
finished.
After the install (booting into normal multiuser operation) the machine
seemed to work fine at first. Notably, X "just works", screen brightness
adjust with Fn-F5/Fn-F6 "just works", iwm wifi "just works", and
suspend-to-RAM with Fn/Backspace "just works".
*BUT*, intermittently (maybe 25% of the time?) after a power-cycle and
reboot, there is what appears to be a system process 'acpi0' infinite-looping
(taking 100% of one CPU core, with 'top' showing ~80% system time for that
processor). Here's a cut-n-paste of the beginning of 'top -S -i -s1'
output in that state, showing the runaway process:
load averages: 1.02, 1.10, 0.86 gold.bkis-orchard.net 00:41:44
134 processes: 130 idle, 4 on processor up 0:19
CPU0: 0.0% user, 0.0% nice, 80.2% sys, 1.0% spin, 17.8% intr, 1.0% idle
CPU1: 0.0% user, 0.0% nice, 0.0% sys, 1.0% spin, 0.0% intr, 99.0% idle
CPU2: 0.0% user, 0.0% nice, 1.0% sys, 2.0% spin, 0.0% intr, 97.0% idle
CPU3: 0.0% user, 0.0% nice, 1.0% sys, 2.0% spin, 0.0% intr, 97.0% idle
Memory: Real: 341M/1548M act/tot Free: 14G Cache: 665M Swap: 0K/34G
PID USERNAME PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND

48374 root 2 0 8952K 15M sleep/2 select 0:09 0.73% perl
Specifying an additional '-H' option to 'top' ("show process threads")
didn't change the output significantly.
FWIW, I have apmd running
# cat /etc/rc.conf.local
apmd_flags='-A -t 60'
vmd_flags=''
xenodm_flags=''
#
apmd appears to be adjusting the CPU clock rate correctly, both now
and on those cold-boots where the infinite-loop problem does not occur.
As I noted above, suspend-to-RAM (via Fn-Backspace, which is the key
combination marked with the usual Thinkpad "moon" icon) "just works".
Is this sort of acpi (?) runaway a known T580 problem? Neither google
nor the nycbug.org dmesg archive show any OpenBSD T580 dmesg, but I do
see occasional web posts mentioning OpenBSD on a T580.
Below I give my dmesg (from the current boot, the one that produced the
above runaway process). What other information would be useful to try
to diagnose the problem?
Thanks,
