Re: Lockups with Quadro FX 3400 + HP xw9300 + 7676
The full lockup that you're reporting looks like a known kernel bug, which is documented in the NVIDIA README in the section titled "The X86-64 platform (AMD64/EM64T) and 2.6 kernels". The odd thing is that you're running a 2.6.11 kernel, so this bug should have already been resolved, unless SuSE did something odd with their kernel build. Can you try upgrading to a 2.6.12 based kernel from kernel.org and see if that helps at all?
For both of these issues, do you have a reliable means of reproducing them, or are they seemingly random?
