Kernel version 2.6.13-rc2 and before correctly detected both C1 and C2 processor states, so when the system is idle some energy and heat is preserved. Now, with 2.6.13-rc3-git8 only C1 gets detected, so no power save.
I am going to try the patch Andrew suggest in this same thread right now, and will report back is this fixes the issue. I inline a (trimmed) diff of two boots, the first with the (working) 2.6.13-rc2 kernel version, and the other with the (non-working) 2.6.13-rc3-git8 one. No changes in the .config file except for the new options appeared in between (some options shuffling apart, the only change relevant to the problem should be the new CONFIG_ACPI_HOTKEY=m): --- boot_stripped-2.6.13-rc2.txt 2005-07-29 19:46:44.000000000 +0200 +++ boot_stripped-2.6.13-rc3-git8.txt 2005-07-29 19:46:59.000000000 +0200 @@ -1,4 +1,4 @@ -dardhal kernel: Linux version 2.6.13-rc2 ([EMAIL PROTECTED]) (gcc versión 3.3.6 (Debian 1:3.3.6-7)) #2 Fri Jul 8 22:06:45 CEST 2005 +dardhal kernel: Linux version 2.6.13-rc3-git8 ([EMAIL PROTECTED]) (gcc versión 3.3.6 (Debian 1:3.3.6-7)) #3 Wed Jul 27 20:53:55 CEST 2005 dardhal kernel: BIOS-provided physical RAM map: dardhal kernel: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) dardhal kernel: BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) @@ -11,7 +11,7 @@ dardhal kernel: DMI 2.3 present. dardhal kernel: Allocating PCI resources starting at 20000000 (gap: 20000000:dfff0000) dardhal kernel: Built 1 zonelists -dardhal kernel: Kernel command line: auto BOOT_IMAGE=2.6.13-rc2 ro root=302 rootfstype=ext3 +dardhal kernel: Kernel command line: BOOT_IMAGE=2.6.13rc3git8 ro root=302 rootfstype=ext3 dardhal kernel: Local APIC disabled by BIOS -- you can enable it with "lapic" dardhal kernel: Initializing CPU#0 dardhal kernel: PID hash table entries: 2048 (order: 11, 32768 bytes) @@ -20,31 +20,32 @@ dardhal kernel: Console: colour VGA+ 80x25 dardhal kernel: Dentry cache hash table entries: 131072 (order: 7, 524288 bytes) dardhal kernel: Inode-cache hash table entries: 65536 (order: 6, 262144 bytes) -dardhal kernel: Memory: 515756k/524224k available (1805k kernel code, 7920k reserved, 835k data, 160k init, 0k highmem) +dardhal kernel: Memory: 515740k/524224k available (1817k kernel code, 7936k reserved, 843k data, 160k init, 0k highmem) dardhal kernel: Checking if this processor honours the WP bit even in supervisor mode...
