Re: Linux 2.6.23-rc3



Hello Michal,

This morning I have booted laptop, for a while fan had been turned off.
But then after a light load (compiling stuff & co), fan was turned on
and now it is still on.

zilvinas@zv:~$ acpi -bt
Battery 1: charged, 97%
Thermal 1: ok, 48.0 degrees C
Thermal 2: ok, 37.0 degrees C
Thermal 3: ok, 46.0 degrees C
Thermal 4: ok, 37.0 degrees C
Thermal 5: ok, 32.0 degrees C
Thermal 6: ok, 20.0 degrees C

Temperatures don't seem to be that high to keep the fan on.

Z.

Hello lkml,

Linux kernel v2.6.23-rc3 booted ok and so far everything is fine. I have
HP Compaq nx9420 laptop (Dual Core).

Just a few things that I found interesting:

1. /sys/devices/system/clocksource/clocksource0/*

$ sudo grep . *
available_clocksource:hpet hpet acpi_pm jiffies tsc
^^^^^^^^^ listed twice ;) not a big deal but still.
current_clocksource:hpet
^^^^ seems selected ;) although in dmesg there are

$ dmesg | grep -i hpet
$ dmesg | grep -i hpet
ACPI: HPET 7FFE59BC, 0038 (r1 HP 309F 1 HP 1)
ACPI: HPET id: 0x8086a201 base: 0xfed00000
hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0
hpet0: 3 64-bit timers, 14318180 Hz
hpet_resources: 0xfed00000 is busy
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ? strange.

Time: hpet clocksource has been installed.

2. ACPI related (?) - one fan is always on, even when system is idling.

It never stops ;)

Hmmm... looks like a thermal trip points problem.


$ acpi -bt
Battery 1: charged, 98%
Thermal 1: ok, 48.0 degrees C
Thermal 2: ok, 38.0 degrees C
Thermal 3: active[5], 47.0 degrees C
Thermal 4: ok, 37.0 degrees C
Thermal 5: ok, 32.0 degrees C
Thermal 6: ok, 25.0 degrees C


In earlier kernel versions it was turned on when needed (mostly during
compilation ...) and then when system is cooled enough fan was
automatically turned off.

3. the same messages are printed twice (2.6.23-rc2 was fine).

Brought up 2 CPUs
NET: Registered protocol family 16
ACPI: bus type pci registered
PCI: BIOS Bug: MCFG area at f8000000 is not E820-reserved
PCI: Not using MMCONFIG.
PCI: Using configuration type 1
ACPI: EC: Look up EC in DSDT
ACPI: EC: GPE = 0x16, I/O: command/status = 0x66, data = 0x62
^^^^^^^^^^^^^^^^^^^^^^^^ 1st time
ACPI: Interpreter enabled
ACPI: (supports S0 S3)
ACPI: Using IOAPIC for interrupt routing
ACPI: EC: GPE = 0x16, I/O: command/status = 0x66, data = 0x62
^^^^^^^^^^^^^^^^^^^^^^^^ 2nd time
ACPI: PCI Root Bridge [C003] (0000:00)


Otherwise I am happy with 2.6.23-rc3. Thank y'all ;)

Best regards,
Zilvinas

Michal
