Hi all, I've just set up a new T480 ThinkPad with OpenBSD 7.4. I have noticed that after sleeping (by closing and opening the lid of the laptop) my fan turns up and one of my CPU cores is fully loaded. `top -U -S root` and `systat vmstat` tell me, that acpi0 is generating a lot of interrupts, close to 2000/s.
Once I had this high interrupt count directly after booting, without even putting the laptop to sleep. Can anyone help me debug this or does someone know of a workaround? >From what I've read I could probably disable certain ACPI functions using bsd.re-config(5), but I'm not sure where to start. Do I have to go through all 49 devices listed in acpi(4)? Greetings, Richard dmesg; the last 22 lines were generated when closing and opening the lid: OpenBSD 7.4 (GENERIC.MP) #1397: Tue Oct 10 09:02:37 MDT 2023 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8200216576 (7820MB) avail mem = 7931973632 (7564MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 3.0 @ 0x9a628000 (63 entries) bios0: vendor LENOVO version "N24ET74W (1.49 )" date 08/15/2023 bios0: LENOVO 20L6SF8C00 acpi0 at bios0: ACPI 5.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT SSDT TPM2 UEFI SSDT SSDT HPET APIC MCFG ECDT SSDT SSDT SSDT BOOT BATB SLIC SSDT SSDT SSDT LPIT WSMT SSDT SSDT SSDT DBGP DBG2 MSDM DMAR ASF!
