So now I was running 2.6.4-rc1-mm1 today and the rratic behaviour came again, ie, idle temps went high. Strange enough this only happens after some time. Comparing dmesg from both, I see this as major differnece: With latest mm-source the as scheduler gets used, though I set elevator=cfq in the kernel line. So either you removed cfq or it doesn't get selcted and maybe anticipatory causes the temp rise? Well, I will test as scheduler with 2.6.3-mm4 tomorrow and report back Prakash PS: here the diff between the dmesgs: --- dmesg2.6.3-mm4.txt 2004-03-02 21:40:07.359583984 +0100 +++ dmesg2.6.4-rc1-mm1.txt 2004-03-02 09:59:49.000000000 +0100 @@ -1,4 +1,4 @@ -Linux version 2.6.3-mm4 (root@tachyon) (gcc-Version 3.3.3 20040217 (Gentoo Linux 3.3.3, propolice-3.3-7)) #12 Tue Mar 2 09:39:12 CET 2004 +Linux version 2.6.4-rc1 (root@tachyon) (gcc-Version 3.3.3 20040217 (Gentoo Linux 3.3.3, propolice-3.3-7)) #3 Tue Mar 2 09:58:07 CET 2004 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f800 (usable) BIOS-e820: 000000000009f800 - 00000000000a0000 (reserved) @@ -11,7 +11,6 @@ BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 127MB HIGHMEM available. 896MB LOWMEM available. -zapping low mappings.
