Ok, thanks for the info.
The question still is: Does Linux throttle immediately on a thermal event (if
one is happening).
You can increase acpi debug level by:
echo 0xf >/sys/module/acpi/parameters/debug_level
echo 0xffffffff >/sys/module/acpi/parameters/debug_layer
If you exceed the passive trip point, is there a "notification" message or
similar in syslog?
Hope this enables notification logging...
If yes, does cpufreq (best monitor with watch -n1 cat /sys../scaling_cur_freq
as shown above) get lowered immediately?
Or does it take another poll (could take about 10s). Then an old bug slipped in
again.
If things are immediately throttled, I'd suggest to close this one documented
as a workaround is to modify the BIOS setting. May be a HW defect which is only
triggered on Linux due to higher power consumption (e.g. of graphics card) or
similar.
If not -> this is the bug.
