Re: debian crashes server (can't use debian ? :-( )

Yep, my "workmachine" has 2 debian's and a win os running and i never
had problems with my debian systems before.

i know. anyway, i'm not going to run 98 on it. if my reinstall of debian
fails i'll try another linux distro to see if that makes any difference ( i
doubt it but i'm going to try it anyway).
Crux seemed nice, vector linux too. But i really don't think this will make
a difference.
(*** i just started my server while typing this message *** )
I just started the server: it booted *nicely* (shrug) into windows 98.
I opened windows explorer et voila. gone. same kind of shutdown i
experienced in linux. haha. so tomorrow, it's back to the computer
store since it ISNT linux related. i never tought it was and now i have
proof. Of course if they weren't able to detect it, i don't have much faith
in there skills either :-(
I'll try to look further myself.
Anyway, again while doing something that accesses the HD altough i
replaced it. hmmm. my the onboard ide controller is faulty?

The crashes that i'm experiencing is mostly noticed when my system boots.
>From the moment the kernel starts accessing the harddisk it fails.
Sometimes it completes the boot and stays up and running for several
days. Sometime it doesn't. It just shuts down as if you would unplug
the power.
I noticed last week that when i booted the system with Knoppix that it
always crashes when the boot sequence is about to access the drive.
Sometimes i runs further, sometimes it doesn't.
As i said, a couple of times it could restart and then i checked the logs,
nothing to be found in there to indicate what could be wrong. I checked
nearly every log in /var/log.
So i have no messages or log files to go on.

Yeah, i have posted before on this problem ( 2 Nov 2002 ) under
"server with debian 3.0 randomly shuts down when booting"
and you had also replied to it :-)
And then some time later i said that it was solved. NOT :-)
I changed the powersupply to a 450 W but that didn't help

* debian woody testing, base install with shorewall, nothing else.
* 2.4.18 bf24 kernel, non customized
* modules: none (everything seemed to work right out of the box
   with kernel 2.4.18bf24. i could be wrong though)
* not running x server, plain base install

* AHA 2940 PCI SCSI adapter
* Guillemot maxtor gamer 32 MB (was in my desktop a while ago
but i wanted a faster card so i "upgraded" my server :-)
* 2 PCI Realtek rtl8139 network cards
* Maxtor 6 GB IDE harddisk (ext3 partitions)
* 160 MB EDO Ram
* Motherboard: DFI 686IPK (Intel 440FX chipset. Supports Intel
   Pentium II CPU up to 266 MHz. 4xPCI, 4xISA (1 shared) ,
   4 x SIMM sockets.)
* Award 4.51 PG Bios
* Plextor PX20 TS SCSI cdrom
* Pentium II 266 Mhz
* 450 W power supply
* sony disk drive

Since the crashes i changed my harddisk, my powersupply and
ran tests by removing the scsi card and scsi cdrom, removing
the isa soundblaster and so on.
Only thing i haven't changed yet is my guillemot graphics card.
Could a graphics card result in crashes while it's only used
when displaying console messages? Maybe it overheats?

2 on the power supply and 1 on the processor

450 w

Nope. Thats another test i did. I plugged my power cable into
another powercircuit to be sure it wasn't the circuit that was causing
the randome crashes.

Room temperature: between 14°C (57 °F) - 24 °C (75 °F)

Interesting. I will try to test the memory too.
You mention memtest386. Are there any other tools to test the system?

It's already at 450 so i don't think that's the problem.

Anyway, thanks for the pointers.
(again, since you answered my very first posts about this problem too :-)
