I'm having the same problem as is described in ticket #689, http://www.netroedge.com/~lm78/readticket.cgi?ticket=689 -- I also have a Soyo K7ADA motherboard, lm-sensors sees an lm78 chip, but when I try to modprobe lm78, I get an audible tone that won't go away and I have to shut the machine down. I've gone over my board trying to figure out what chip it uses, and I can't find anything that explicitly says "lm78" but can't find anything with a similar name either (sorry, I'm not that experienced with hardware and don't know how to recognize a sensor chip when I see one -- any hints?) I've scoured the net and Soyo's various web sites looking for information on what chip it actually uses, but haven't found any information. I see that the ticket was closed; I'm wondering whether a solution was ever found? I'm having frequent sporadic glitches of various sorts (not seeing disks, crashing or rebooting in the middle of long compiles) and I'm very eager to find some way of monitoring the CPU temperature to see what the problem is. I'm trying to figure out whether I should buy a different motherboard (anyone have any recommendations for an Athlon XP/DDR motherboard that works well with Linux, lm-sensors and ACPI?) or if the problems are elsewhere. Thanks very much for any help! ...Akkana
