Hello.
dmesg here: https://clbin.com/ZVk9N
I have a clean OpenBSD 7.6 install on my ThinkPad T580. 8th gen i5 CPU, 16GB
RAM, NVMe drive.
I did a syspatch after installation.
When I do a fresh power-on boot I noticed my system is running extremely
slow. Literally everything is running slow, even pressing enter in the text
console. top -S is showing "acpi0" command to be utilizing 85% of the CPU,
but in terms of core usage it appears to be maxing out core zero and not
touch the three other ones. Also the laptop fan is running at high speed and
blowing hot air so the battery life is poor.
What I noticed is that if I do a reboot (so not a power on boot from cold)
then the problem does not manifest at all. Laptop fan is silent, all cores
are properly idle and the whole system is very responsive. However, if I
then close the lid of the laptop apmd puts the computer to sleep and upon
waking up the acpi0 issue manifests again so I have to reboot again to get
rid of the problem.
I tried to disabling a lot of things in BIOS but nothing helped. BIOS is up
to date, I flashed it a couple of months ago.
In dmesg I cannot see a problem, but I have attached it above as a link.
Please advise how do I proceed with troubleshooting this.
Search the lists, this has been reported and the fix described dozens of times.

Thank you. Turns out the fix was to disable Thunderbolt in the
BIOS/UEFI. I have been testing it for the whole day and I can no longer
trigger the issue.
