laptop running hotter after kernel recompile


I posted something similar to the software forum(sorry for posting again)
Toshiba A75 S229 - Fedora Core 3
Ok I recompiled my kernel and ever since then my computer has been running warmer(just feels wamer) and the battery meters on gkrellm is wrong. the gkrellm meter used to say i was using around 0.7%/m but now it just jumps up 1.2%/m. Im pretty sure I configured everything correctly for the kernel. My .config file is here
what could be wrong?? Oh one more thing even when i boot into an old kernel the batter meters and temperature are screwed up since i recompiled the kernel.
old kernel - 2.6.10
new kernel - 2.6.11.4

THanks,
Paul

hi there,

i see that some acpi options are compiled as modules. are you loading these? why not compile as builtin?
an important thing to keep the laptop cold is cpufreq? are you running some script or daemon - cpufreqd - to control it?
rebooting in the old kernel should not be a problem. how did you upgrade your kernel? by hand or by fc3 apps?

some mods won't be happy about that. try to avoid it from happening again.

[EDIT] i see now that you don't have acpi_toshiba in your kernel. why? is your model not compatible somehow?

Your ACPI settings should be compiled into the kernel, not as modules. Will save you some problems.

I upgraded my kernel by hand. I updated .config, make modules, make modules_install, make install. Also here is a sample from the .config file
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=y
# CONFIG_CPU_FREQ_STAT_DETAILS is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_TABLE=y

i did compile Config_cpu_freq in it. Also I have a toshiba that has the phoenix bios, not a toshiba bios. That is why I didnt put the toshiba acpi stuff in it.
Here is part of what I get from dmesg.
p4_clockmod 4492 1
button 5136 0
battery 7684 0
ac 3588 1
md 38224 0

lookes like the acpi modules are running. also, another error at boot time says something to the effect:
raidautorun: couldnt start device /dev/md0 said something like that. what could that be?

thanks for your help,
Paul

hi there,

i suppose that the overheating problem is solved.
now, your next question has nothing to do with acpi.
you have it or you compiled in your kernel support for RAID hardware. is that correct?
check if the correct options are selected in the kernel config.
at least is what i read in your message....

regards

do i even have raid?

I have a laptop. Only one hard drive. Im a little confused on this raid stuff. Do I need it compiled in. In my config file I didnt select raid to be included. I read somewhere if I just comment out the following line from /etc/rc.sysinit it wont give me that warning anymore.
echo "raidautorun /dev/md0" | nash --quiet
Is it safe to do that?
Thanks for your help,
Paul
