All,

Not sure how many of you this applies to, but I recently upgraded my x86_64 system to Fedora 17 (x86_64). In the process, it re-enabled the vesafb framebuffer driver for the console graphics. The NVIDIA driver module burped a warning about this to my messages logfile, suggesting it could destabilize the NVIDIA driver. I immediately noticed an increase in computation errors on GPUGRID tasks. I disabled the vesafb driver and my tasks are running normally again. Anybody having weird computation failures on linux should make sure they have no framebuffer or other video drivers loaded other than NVIDIA!

To disable vesafb, I added the following to my kernel boot parameters:

linux video=vesa:off vga=normal
