We are suffering from server abends on a Dell PowerEdge 2950.

The server is running:
Netware 6.5 SP7
Edirectory 8.8 SP2
It has the Netware USB patch for the Dell "reboot hang"

The server has BX2.LAN version 3.70 from september 10 2007

The server can run normal for a few days, but then always abends on "ethertsm.nlm" at random times.
After the abend the server screen is black with no response to the keyboard.

To resolve the problem I have performed:
- Update bios, firmware from the controllers / drac board / etc
- Disabled the first onboard nic and enabled the second one with completely reconfiguration of the driver (remove driver and reinstall with hdetect) + tcp/ip.

I have attached the abend log, maybe some can analyse it a bit.

Many thanks
