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. > ==== > > There are no additional kernel patches in the build. Yeah, ok, let's say you're running pretty much an upstream kernel. > These boots are consecutive and are all from the same stock 5.12.0 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. > $ make menuconfig > ... > > This config option is not listed and is not changeable: 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.
