- Hi
- We have been having a similarly weird experience with one of 5 R4K's - it
- was fine until the video board was installed. I have found that the crashes
- stop if I switch off all networking and run in stand-alone mode. There were
- similar panic messages but ours were all Unrecoverable ECC errors.
- Our local SGI people are aware of it and working on a solution, we will run
- either with the svideo board or networking until then.
- I will re-post if a solution becomes available - or even an explanantion 8-)
- Neil
