System Locks up overnight

[samsc]

sounds even more like a scsi or cabling problem.

try swapping the cables, or removing the cables from the machine thats not working correctly.

i think its these terminators.

they mount directly in front of the drive in a pass-through configuration inside a g5 - if you are using internal drives.

well i have replaced the SCSI cables on the 2 older machines and the "lemon" still locked up on me but durring rehersal. I am now going to swap out the SCSI card. The odd part is the fans defaulting to high. Or does this happen any time a G5 locks up?

fans going high means somekind of hardware or operating system fault.
That means the OS has stopped running!

This is not a catalyst software fault.

Hugh seems to think that there are wierd permissions issues in the operating system installs as well, that might cause this.

Send him an email.

Hi Guys,

Just saw this thread.

I had this once.

My machine was left on ( I cannot remember if movies were playing or not).

I heard the fans speed gradually increase and keep increasing.

I have come across this behaviour before when I fitted a bad Atto SCSI card whilst upgrading a G5 to a SCSI drive; (fitting a good card solved the problem).

Hugh described it as a "kernel panic".

The odd thing is it happened when I was doing absolutely nothing at all with the machine but I was in the room working on something else.

Pretty sure this was on G21.

The interesting thing is the machine it occurred on doesn't have a SCSI drive, just a WD Raptor (Richard its the one you gave us).

At the time I just hit the reset button sharpish as the speed of the fans was increasing in an unhealthy manner.

It has not occurred since and I though nothing more of it until now.

fans going on means total system crash or hardware failure.
usually intermittent.

Nothing to do with Catalyst or pixelmad.

recent os builds have not seen this happen so much for me.

i had a broken fan on a graphics card that used to cause this to happen.
heat....

[samsc]

Came up with an idea to check whether its an OS install problem or a hardware problem.

Solution:

Buy a new hard disc.

1. Install totally new system on disc

2. if the computer still crashes - its a hardware fault

3. if the computer doesnt crash - its an os install problem.

Seems to me that i could just swap the scsi drives between 2 machines and see if the problem moves. The only bummer there is that the bad machines brother is going to Austraila for a gig. It will have to wait a bit.

did you update the flash roms in the atto cards?

they definitely did several rom updates last year.

on the atto site - this is refered to as firmware

http://www.attotech.com/

they also did driver updates as well.
