** Description changed: This bug is present on Inspiron 6400 cpu intel core duo T2500, Ubuntu 6.10, kernel 2.6.17.1-10.34 generic. When I leave my dell laptop without moving the mouse nor typing on the keyboard for more than 5 minutes, the cpu usage of the 2nd core goes to 100% and it remains locked at 100% unltil I move the mouse again (or press a key). This bug seems to be appeared after last week kernel update on my Ubuntu 6.10 (current kernel version: linux-image-2.6.17-10-generic 2.6.17.1-10.34): http://ubuntuforums.org/showthread.php?t=318005 Actually I've tested the following, but none of them changed the bug behaviour, still 100% load on 2nd core after 5' of inactivity: - Disabling the fan regulator daemon "dellfand" - Disabling acpi services from "adnimistration->services" menu - Disabling powernowd service from "adnimistration->services" menu Then i've tried this way: - Compiling a custom kernel version 2.6.19 from sources with the same setting of ubuntu's default. ..and the bug changed so that after 5' of inactivity the 1st core (and - not anymore the 2nd core) goes 100% of load, this does not resolve the - situation. + not anymore the 2nd core) goes 100% of load, this doesn't resolve the + problem but maybe confirms it is something kernel-related. Please tell me if there is a useful log i can attach to this bug request. This bug is very critical for me because i'm not allowed to leave the - laptop for more than 5' unless i risk. cpu overheating. + laptop for more than 5' unless i risk cpu overheating.
