Suse 10.1: crashes!!

[7280]

Hi,
I've installed suse 10.1 on my desktop three days ago.
I work fine almost all the morning but after few hours system becomes slower and gives strange outputs.
This system is mainly used to connect remotely to other systems (ssh), so I use only konsole (KDE) and firefox to navigate (very poor usage!).
Very strange behaviors are:
- command vmstat, eg:
vmstat 1 --> returns 1 line output and the "Floating point exception"
- command date, when system becomes slow, this gives error outputs, eg:
date
Fri Jun 30 09:02:54 CEST 2006
date
Fri Jun 30 09:02:56 CEST 2006
date
Fri Jun 30 09:02:56 CEST 2006
date
Fri Jun 30 09:02:53 CEST 2006
I tried to syncronize date with an ntp server, it goes fine for a few
seconds then errors again.
Also tried to manually adjust it by yast2 'timezone' but without any result.
The only way to bring the system working normal is to issue hard reset of the system (not reboot because system stops responding.. hard reset!!). It's the first time that I'm obliged to reset a linux machine.. hey, windows seems working better!!!
Is there any known bug on this release?
I have also disabled a lot of unused services (with chkconfig) but problems still remain.
I really thinking to install some other distro.
Please help!!!
Thanks,
Tarek

Have you tried ps? sar? top? See if something is consuming CPU cycles.

Nope, nothing is consuming CPU.
Just after a few hours it stops working normally.

Today I'm back from the weekend (and this desktop was on) and again strage errors:

REally don't know what to do.
Now if I reboot everything will be fine for some hours and then again problems.

Sounds like hardware to me........
What do your logs show ?
What type of system is this? IE, Processor, how much Ram ect...
Are overclocking ?

 

[BocaBurger]

Hardware would not normally slow things down, unless there is a thermostat on the CPU tied to frequency or something like that.

Shut down, reseat everything movable (chips, cards, RAM) and see if that helps.

Before touching anything see if it is very hot.

Hi,
it's IBM hardware, NetVista 8309-78G.
Something changed when I disabled powersave and apc services and from bios I disabled hardware standby (disk, mem ...).
Now I have problems only after weekends. On monday system clock is wrong and I have all those syntoms.
After a reboot things are fine.
But now I don't know what else I have to disable.
Thanks again,
Tarek
