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: Linux version 2.6.5-1-686 (tretkowski@rollcage) (gcc version 2.95.4 20011002 (Debian prerelease)) #1 Fri Apr 9 12:46:05 CEST 2004 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000001dffc000 (usable) BIOS-e820: 000000001dffc000 - 000000001dfff000 (ACPI data) BIOS-e820: 000000001dfff000 - 000000001e000000 (ACPI NVS) BIOS-e820: 00000000fec00000 - 00000000fec01000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 0MB HIGHMEM available. 479MB LOWMEM available.
