Only if it runs whatever you like to do with your computer faster than a
non-SMP kernel.  SMT (multithreading) is not always faster.

It is unlikely that a SMP kernel would cause a freeze *directly*.  BUT SMP
is known to cause badly written/buggy code to show its ugly face, so it is
very possible indeed that something in your kernel is objecting highly to
the SMP.

Are you using ATI or nVidia proprietary kernel modules?  If so, get rid of
them and see if the crash goes away.  If it does, you know where to direct
your complains.

To change the default Sessions manager type "updates-alternatives --config w-session-manager" as root and then select the startkde option and press enter.  I change KDE to my default sessions manager on all of my computers.  As for the other problems, SMP is only needed for your processor if it supports HyperThreading.  If it does, and you turn it on using a SMP kernel, you will appear to have 2 processors.  If you do not see 2 processors, you do not need SMP.  You mentioned full filesystems,  the output of "df -h" would help if you emailed this to the list.

I have a Pentium Four processor with 3.06GHz speed. As far as I can tell, this means that I am eligible to use a 686-smp kernel. Though in comparison to the non smp kernel it seems to be much faster, an odd thing is also happening which I can only attribute to the smp (since I have not really seen it on the non smp kernel). My computer is doing some big-time freezing. It seems to be random, happening a few hours after I turn on my laptop; or only a few minutes. I have to manually do a hard reboot, which means it needs to run fsck which means data can be lost or corrupted (aside from it possibly damaging the whole computer and generally being a very big pain in the arse). 

I'd like to know your opinions. Is this freezing due to the smp? If so, why? How can I fix it?

I thank you kindly in advance.


To add a bit to the fun, I can no longer log in under my user name from KDM (I've not tried GDM). I can, however, from a console. But, I do not know how to start KDE from a console: Doing startx gives Gnome, which is not what I use. 

I believe that the problem is with X. I could be completely mistaken. I'm thinking of purging all of it (apt-get remove --purge xserver-xorg xserver-xorg-dbg and maybe xserver-xfree86). Is this a good idea?

I would be very grateful for any help whatsoever as my system is really becoming unusable. Not to mention data is being corrupted every time I must do a hard re-boot. And it hampers me from doing my work.

I thank you most kindly in advance.

Willie,

   Yes, this has happened to me also.

   Note that 2^32 hundredths-of-a-second = 497.1027 days,
   which seems like a plausible explanation of what happened.

   It's also the case that the CPU time of a process rolls over
   after the same period of time (497+ days).  Yes, this has happened
   to me.  Really.

   Hah! -- whoever designed such short time limits?
   O they of little faith!

Cheers, Joseph

It does actually say on the site..

http://counter.li.org/reports/uptimestats.php

"NOTE: The Linux kernel (at least up to 2.4.2) has a flaw: It computes
the result of the "uptime" based on the internal "jiffies" counter,
which counts the time since boot, in units of 10 milliseconds. This is
typecast as an "unsigned long" - on the Intel boxes, that's an
unsigned 32-bit number. "

Cheers,
Al.

Are you using ATI or nVidia proprietary kernel modules?  If so, get rid ofthem and see if the crash goes away.  If it does, you know where to direct
your complains.If you are rederening to what is currently in my kernel, I am using the standard linux-image from the Debian repository and, subsequently, I do not know. I do, however, intend to build my own soon. If, however, you are refering to X, I asked it to use ATI for my monitor since this laptop's monitor is indeed ATI. But, I'm not quite sure what you mean.
