I see on our GPU compute nodes, configured by a colleague, we use this kernel line during install:
# rocks list bootaction | grep gpu gpuinstall: vmlinuz-6.0-x86_64 initrd.img-6.0-x86_64 ks ramdisk_size=150000 lang= devfs=nomount pxe kssendmac selinux=0 noipv6 ksdevice=bootif xdriver=vesa rdblacklist=nouveau nouveau.modeset=0 This is RHEL6 (Rocks 6.0) on HP SL250s hardware. I think they didn't boot correctly without blacklisting nouveau. Hope that helps.
