flooded by "CPU#0: Running in modulated clock mode"
From: Alexey Mahotkin
Date: Wed Apr 21 2004 - 12:32:08 EST
Zwane and all,
I'm running 2.6.5, compiled for i686 architecture, on Celeron 1.8GHz.
Motherboard is ASUS P4S800-MX. The machine has 1U form-factor.
Usually processor runs at ~40C, according to lm-sensors (and BIOS
agrees with it).
When I start CPU hog (prime-net client), the temperature rises to ~62C
in several minutes. After that I'm getting a swamp of messages:
CPU#0: Running in modulated clock mode
CPU#0: Temperature/speed normal
CPU#0: Temperature above threshold
CPU#0: Running in modulated clock mode
CPU#0: Temperature/speed normal
CPU#0: Temperature above threshold
[ ...endless... ]
When I stop it, messages stop immediately, and processor cools down
back to 40C.
However, according to google, maximum Celeron temperature must be
somewhere near 80C. Also, AFAIU, if it were overheating, I'd get a
single message about "Temperature above threshold".
Why is it flooding me on KERN_EMERG level? How can I change the
temperature threshold?
Should I try noapic? Should I try acpi=off?
Thanks,
Here is my dmesg output from the start:
