Every time I remembered I had to do sensors testing it was the wrong moment. I was either nowhere near the laptop or doing something else that I could not interrupt there and then. :/ > I don't get you. The adm1021 module is an i2c-only driver.

I can't believe you get any result using only > the i2c-core, i2c-proc, i2c-isa and adm1021 modules. It gets whackier. I get the same results from both 2.4 and 2.6 now and they're different to before! Joy. Everything works fine at first under both. No immediate slowdown. No dmesg being filled with whackyness. Nothing. I then put the system under load by compiling the kernel and the slowdown hit. Under 2.4 I'd lose the odd keystroke and things would go very slowly. A subsecond beep would wind up taking multiple seconds. Under 2.6 I'd get multiple char repeats and lost chars and things again would go slowly. rmmoding the modules under either version did not help. The sensors data was whacky too. here's one snapshot: thmc10-i2c-0-4d Adapter: SMBus PIIX4 adapter at 2180 Algorithm: Non-I2C SMBus adapter Board: -101?C (min = +20?C, max = -101?C) CPU: -101?C (min = +20?C, max = -101?C)ALARM (LOW,HIGH) Before this one the CPU temp was 61degC but the laptop fan wasn't working overtime and I was not burning my fingers on the kboard. Running it again showed CPU at 64degC and the thmc line turned into max something or other. I tried to get a snapshot but I had to turn my laptop off to recover and the file did not make it out of the cache. > What if you load i2c-piix4 first, and then adm1021?
