You're probably using a notebook. Your CPU is running slower to save
power since you're probably not doing anything CPU-intensive.
Open a terminal and do 'cat /dev/urandom > /dev/null' and then look at
your CPU speed. You should find that it will climb to 1400 MHz.

Caro, do a "$ grep -i cpufreq /boot/config".

Your CPU is speedstep capable. Most modern distros include a daemon
for adjusting CPU speed based upon load.

'cpuspeed' in Fedora/RHEL. Debian probably offers a dozen different
ones most of which I've never heard of :)

It's probably a notebook that you started unplugged from the mains power.
Mine is stupid enough to believe that I *want* to save power if I plug
the mains *after* powering it up ! And there's no way to force it to
switch from 600 to nominal freq afterwards ! So I have to connect it to
the mains first.
Regards,
Willy

Isn't there a daemon to do that?

If you say this based on 'cat /proc/cpuinfo' output: isn't it true that
/proc/cpuinfo is static, and doesn't necessarily reflect the actual
speed of the processor?

no that's not true.

Hallo!
You could try:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
It's possible that you have chosen "power_save".
You can see possible settings in
sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
Try "performance"!
Then you should get your 1,4 GHz.
But be aware, that this is not powersaving!
Maybe you can play around with it.
A good possibility is to install an userspace application for governing
the cpu-speed lik cpufreqd

Hi!
I'm almost finished with my driver for the monochromatic ST7565 LCD, but I'm
dealing with a bug that I could't solve by the entire day.
It was designed to be run as a module, and it's living together with another
display that already owns the console devices. So, when I load st7565's
module, it just skips take_over_console() code in fbmem.c and starts to
accept write()'s on it.
By the way, I got some demo applications from MicroWindows (microwindows.org)
that starts to get more information from the driver. It looks like when they
request st7565_set_cmap(), some invalid pointer is accessed and the driver
just dies:
Unhandled fault: external abort on non-linefetch (0x00a) at 0x4001a004
pgd = c3d78000
*pgd = 0bcaf001, *pmd = 0bcaf001, *pte = c4a5e0b3, *ppte = c4a5eff2
I've looked at other drivers' routines, such as hgafb, and it really looks to
be everything on the right place. I got the impression that this error could
be happening due to the fact that my driver didn't get the console's
ownership, so I've disabled the other driver and compiled st7565 built-in,
but then the driver dies with the same message at take_over_console().
Does anyone know if hgafb is a working driver that I could rely on? Also I got
confused by the need to use or not a color pallete -- probably I don't need,
as I'm working only with black/white, but at this time I'm no more sure about
anything at all :-)
I'm also confused about the "setcolreg()" function passed to fb_get_cmap().
What should it do? What's the meaning of its 1st parameter, "regno"?
If someone could take a time to give a quick look on my set_cmap() routine,
I've uploaded the code here:
http://cscience.org/~lucasvr/etc/st7565.c
Thanks in advance, any help will be very appreciated!

Hi again,
I've fixed the non-linefetch error: I was passing the virtual framebuffer
address into fix.smem_start instead of the physical one. Things got weird
then when fb_writeb() tryied to write on that address ;-)
Cheers,
Lucas

Yes, and we all follow that counsel to the letter, I assure you ;).
If it helps to track this thing down, here's a call trace I collected from
hitting Alt+SysRq+P while I was getting the "flushing like mad" with powers of 2
during a shutdown. Again, this is NOT an oops, so I don't know if it will be as
useful. Also, it was copied by hand to paper first, then to this email, so
there may be a couple typos in there, sorry :(. It also may be slightly out of
date-- this a bk pull pretty much right after the sync to 2.6.0-test3.

I think you can just add some combination of "rw" and/or "rootflags=0" to your
command line to do it. You may also need to bypass the remount in your
initscripts. I did this by using "init=/bin/sh" to boot once, then commenting
out the relelvant part of my init script, then rebooting. You may also want to
add read-write to your lilo stanza and rerun lilo. I also did an "rdev -R 0" on
my vmlinuz image. Sorry, I'm not sure which of these steps are really necessary
and which just add to the confusion, but it "works" for me.

No. You can have the kernel initially mount the partition read-write. IIRC,
you can use rdev and/or kernel command-line options to acheive this effect.
It's just a band-aid for the real problem though, if you really need to get into
your box.

He shouldn't be using reiser4 for anything other than bug finding and
stress testing. Given how extensively we warn people that, I assume
this is just a toy installation without any real data on it for the
purpose of seeing how fast he can crash it.....

Yes, this is right. Moreover, read-only mode is yet unsupported.

Yes, I reported the same problem a couple weeks ago, but got no response. For
me, the error occurs on startup when the initscript is remounting / from
read-only to read-write. I was never able to "solve" the problem, but I can
kind-of work around it by commenting out the remount in my initscript and having
the kernel mount / read-write initially (using rdev). Sadly, the same problem
manifests itself on shutdown sync, so it's never able to complete a "proper"
shutdown.

Thank you for the report. Yes, it is a bug.
Is your reiser4 partition mounted on /? Can you describe what linux system
did you put on reiser4?

I am using CRUX ( built from scratch distro ), yep, I am using reiser4 as
