Re: NVRM: os_schedule: Attempted to yield the CPU while in atomic[...] [260.19.21 x86
I think the problem came up with the update to the latest xorg 1.9. On ubuntu 10.04 everything was fine with driver 256.xx. If I revert to this version under ubuntu 10.10/xorg 1.9 that produces the same results.
I have also eliminated a HW related issue.
