Subject: Athlon Thunderbird, Abit KT7 Raid, Kernel 2.4: DESKTOP FROZEN!


My box: Athlon Thunderbird 900 MHz, MotherboardAbit KT7 Raid,
Kernel 2.4 (the one that comes with Red Hat 7.1 no updates)

I get apparently random desktop freezing.

Last time:

I was just doing nothing so the screensaver
was on when I noticed the screen was frozen. Nor the keyboard
neither the mouse worked. No combination of CTRL-ALT keys.
Only choice left: reset. I did it. When it booted again I got a

Kernel Panic: Attempted to kill the idle task
In idle: not syncing.

(by the way: what is the SysRq magic or something similar?
Does it help? Which keys??)

This time I had to unplug the computer. After 5 minutes I tried again.
In many trials I got hundreds of errors. These:

-After checking /root (passed), it stopped checking /home (failed)
and trying to repair it with fsck gave no result (when the computer
tried to reboot, it freezes again)

-After checking both /root and /home (passed), it stopped at sshd
saying: /etc/rc.d/rc line 117 951 segmentation fault $i start

-At the end of the startup, black screen and message:
Id "x" respawning too fast disabled for 5 minutes (and waiting
produces the same message again: I had to unplug)

-Inside KDE, trying to open anything gave an error related to
inode and in a few seconds X was disabled again for 5 minutes.

Since somebody tells me the Oops is important, I noticed that
when this appeared it was 0002. If this helps..

After a couple of hours I tried and I was succesfull. Now it seems
to be everything ok.

Anyway, a desktop freezing happens every now and again and
no ctrl-alt-anything combination works. Just reset.
This is very dangerous, and even if so far the fsck was always ok,
I feel my data are at high risk this way.

At Red Hat support I got this suggestion:

Is this really a KDE problem? I myself doubt...
It could be a kernel problem or maybe hardware (I checked
all the ram and removed one, but freezing is still there)

Thanks for any help, I am in trouble!!

I've had almost identical problems using Redhat 7.1 (2.4.2-2 kernel) on
Athlon 1.2 GHz Asus A7V133 with the VIA on-board IDE (686b).

Try switching to the other on-board IDE controller, should be HTP370 IDE.
It's probably the VIA southbridge that's causing you these troubles. I
upgraded my kernel to 2.4.5 and 2.4.6 and nothing helped for me (I have a
686b, you have a 686a). The only thing I could do was switch to my on-board
Promise IDE controller. I have no idea what the HTP370 is, but I'm guessing
it won't cause you problems like the VIA will.

You could try compiling a new kernel 2.4.5 or 2.4.6. There were many IDE
fixes between 2.4.2 and 2.4.6. Especially with the VIA stuff I think,
thanks to Vojtech Pavlick. However, I never got my VIA controller to work.
Even if I disabled all DMA it still crashed the kernel every time.

Hi Antonio,

You can find more on this in the kernel source:
linux/Documentation/sysrq.txt

Hmm, I have a similar machine.
K7-800, KT7 RAID, 2.4.5 kernel (was .0 at install time).

Err.. attempted to kill the idle task? Are you sure you don't have an
overheating processor?

SysRq will only help if the machine is responsive; and then even still
it's not going to correct issues like overheating processors and etc.

Shhouldn't be a problem with KDE. It *could* be with X, since (unless
you're using the framebuffer driver), it's directly accessing the
hardware.

Try starting up to a console and building a kernel with fb support, and
then use X through that and see if that solves any problems. (I haven't
had a single crash since; just that, for some reason, the sysrq key gets
disabled on startup and occasionally a framebuffer program will crash and
take my keyboard along with it. "Oops".)

Try to compile a kernel without the Athlon optimization (just K6...).
