Actual Results: Occasional kernel crashes. System is left dead. Enterprise computing showstopper. Additional info: Crashes occur randomly. The chance of crash seems to be about 5%, and increases withthe amount of data being transported. Filesystems containing more than 6Gb seem to crash more often than those containing a few tens of megabytes. In the above script, /nfs/otto is automounted with NFSv3. Nfsstat looks normal before crashes. The crash usually occurs in the tar phase. Machines are Dell Precision/340 with Linux installed and up2dated.
thank you for reporting this nvidia bug report. However you reported it to the wrong company. Red Hat does not support the NVidia binary only kernel modules nor can fix bugs in them (and this is a very frequently reported BUG in the nvidia module). Please report your bug to NVidia instead.
