Hi,

we have some stability problems with our DSS system. After several hours (2-72h) the system freeze. No keyboard inputs possible, no blinking cursor, no response to ICMP echo (ping).

We have tested the system over one week with memtest without any error. After booting DSS with ACPI activated (BIOS and DSS boot parameter) the system runs about 2-24h. After deactivating ACPI (+APM and IOAPIC) in BIOS and DSS (boot parameter) the system runs a bit longer (about 1-3 days) but also freeze.

We have tried the 32-Bit and 64-Bit MP Kernel, but no better result.

Here some informations about the system:

Tyan K8HM (S3892) Motherboard
2x2,4 GHz DualCore Opteron
Serverworks Chipset
4 GB RAM
BIOS 14.6.2007 V1.0.6 / Ami Bios 08.00.11
IPMI Card
Areca 1280 PCIe RAID Controller
2xIntel Quad GBit Ethernet (PCIX)

Any suggestion?

So long
Michael
