This is why the tags contain -arch1 etc. For example, see https://git.archlinux.org/linux.git/log/?h=v5.11.16-arch1 , which adds 6 commits on top of the upstream "Linux 5.11.16" release, while https://git.archlinux.org/linux.git/log/?h=v5.12-arch1 only contains the long-standing "unprivileged_userns_clone" patch and the version number change, making it essentially vanilla.

Yeah, ok, let's say you're running pretty much an upstream kernel.

Yeah, that's weird. Box seems to boot fine in some cases. There's
[ 26.864040] ACPI: OSL: Resource conflict; ACPI support missing from driver?
[ 26.874541] ACPI: OSL: Resource conflict: System may be unstable or behave erratically
Dunno how relevant this is - it probably has been the case since forever.

Bah, sorry about that. Use this small hunk ontop so that you can disable
it in menuconfig:
---
diff --git a/drivers/thermal/intel/Kconfig b/drivers/thermal/intel/Kconfig
index ce4f59213c7a..8c1376a20b54 100644
--- a/drivers/thermal/intel/Kconfig
+++ b/drivers/thermal/intel/Kconfig
@@ -9,7 +9,8 @@ config INTEL_POWERCLAMP
user interface is exposed via generic thermal framework.
config X86_THERMAL_VECTOR
- def_bool y
+ tristate "X86 thermal vector"
+ default y
depends on X86 && CPU_SUP_INTEL && X86_LOCAL_APIC
config X86_PKG_TEMP_THERMAL
---
and with it ontop, boot it the aforementioned way.
And then pls build 5.11 which doesn't have the therm_throt patch - I'd
like to see if that therm_throt thing is even loading. Because I don't
see something like:
[ 0.302411] mce: CPU0: Thermal monitoring enabled (TM2)
in your dmesg. Could be some detection failure due to the change when
those happen. Althouth they shouldn't but who knows.
I have a similar box as yours:
[ 0.305858] smpboot: CPU0: Intel(R) Pentium(R) Dual CPU E2180 @ 2.00GHz (family: 0x6, model: 0xf, stepping: 0xd)
a bit newer stepping and AFAIR, it boots fine but I'll try your .config
there to check just in case.
Thx.
