Default Re: latency problems with binary nvidia drivers

Unfortunately I cannot get this problem resolved. I checked the following things without any luck:

- no or full preemption
- pci=nommconf,nomsi,routeirq (...)
- noapic
- nolapic
- experimented with new 2.6.19 options (e.g. CONFIG_HT_IRQ)

No matter what I do: a few Xorg <-> VT switches already result in buffer underruns with my DVB card. The open source nv driver instead works just fine... no matter what I do, I am unable to force a underrun.

This really points to the nvidia driver. Is there anything I can do to help identify and fix this problem?

Thanks again...
