Public bug reported: 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 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. ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- 100% cpu load after 5' of inactivity https://launchpad.net/bugs/77106 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
