You need to reproduce this without the nvidia modules loaded.

Mar 25 19:55:47 fc6host kernel: NVRM: bad caching on address 0xc0ca4000: actual
0x23 != expected 0x63
Mar 25 19:55:47 fc6host kernel: NVRM: please see the README section on Cache
Aliasing for more information
Mar 25 19:55:47 fc6host kernel: NVRM: bad caching on address 0xc0ca4000: actual
0x23 != expected 0x63

These are from the nvidia driver.

I have similiar problems on some of machines. On one "apcsmart" daemon from nut
is hanging, after some time machine crashed. On another one xen's guest domain
crashed after some time. Friends PC crashes after aprox. 15 minutes.

With older kernels it works without problems.

Nvidia problems should be reported to nvidia.
