Is this a single or multi-cpu system? undersys -> multi-cpu (dual socket) I would like to see the contents of /proc/cpuinfo. undersys -> attached > Micro code was working on 2.6.29 and 2.6.39 , then I jumped to 3.0.6. I admit I don't quite get it for now. While the device probing logic was modified a lot in the coretemp driver of kernel 3.0, the microcode check did not change, so I just don't get why the new driver would behave differently from the previous ones in this respect. For testing purposes, I made the 2.6.39 version of the coretemp driver available as a standalone driver: http://khali.linux-fr.org/devel/misc/coretemp_old/ (Instructions at http://khali.linux-fr.org/devel/misc/INSTALL ) I would like you to test it on your 3.0 kernel and report whether it is working or not. You'll have to rmmod the original coretemp driver before loading coretemp_old, you can't have both loaded at once. If coretemp_old works, then please rmmod it and modprobe coretemp again, and see if it then works. undersys -> I built your module(coretemp_old), works fine no kernel opps. The only lines printed to "dmesg" are :- [ 133.603204] coretemp coretemp.0: Errata AE18 not fixed, update BIOS or microcode of the CPU! [ 133.603277] coretemp coretemp.1: Errata AE18 not fixed, update BIOS or microcode of the CPU! [ 133.603329] coretemp coretemp.2: Errata AE18 not fixed, update BIOS or microcode of the CPU! [ 133.603379] coretemp coretemp.3: Errata AE18 not fixed, update BIOS or microcode of the CPU! If i remove it and then attempt to re-probe the new one, the new one fails. -- Jean Delvare http://khali.linux-fr.org/wishlist.html Hi Jean, Answers are inline. Thanks for your time!
