BUGGY CUDA DRIVER

I came across this when
Install linux version of devdriver(270.41.19) which is at the cuda download page for CUDA version 4(64 bit)
After installing the driver, System is not booting,
stops with message
“libfcoe_device_notification:NETDEV_UNREGISTER lo”
I am using RHEL 6.1(Santiago) workstation.
Is this a known issue or a bug?
