hangs on Nforce2 & kernel 2.6.4

[Pim Bliek <bliekp@pingwings.nl>]

Hello,

I am experiencing total freezes of my system when stressing my hard disk. When 
I normally use it, no problems. But when I move big files around, or do a 
find / -name somefile for instance, my system freezes after some seconds...

I have an Asus A7N8X deluxe motherboard with Nforce2 chipset. I have a Western 
Digital 80 GB HDD connected to the PATA port. I use a custom self-compiled 
2.6.4 kernel on Debian Unstable.

Unfortunately, no errors in /var/log/syslog ....

Anyone else experienced this problem? Or maybe someone knows how I can dig 
deeper into this problem? I am a bit lost...

Best regards,
Pim Bliek
