[Users] I/O stall with SuSE 10 Kernel

[lst_hoe01 at kwsoft.de]

Hello

I have setup a OpenVZ Server for the development with the SuSE 10 
Kerenl found at http://openvz.org/download/kernel/suse10/
Teh machine has been running fine until this morning. It first get 
insane slow and then simply stops doing any file IO at all. It was not 
loaded by any means before and i can found no error messages in the 
logfiles. The only way to get the maschine up again was by 
power-cycling. The Hardware we are using runs fine on other heavily 
loaded SuSE 10 machines :

- Tyan Thunder K8SD Pro with 2xOpteron 248 and 4GB ECC RAM
- ICP Vortex GDT6513RS RAID Controller

No additional PCI cards.

Can anyone give a hint where this problem might come from?

Thanxs

Andreas
