ESX 3.0.1 --> 3.0.2 upgrade failure, unable to boot

This is about the 12th server I have upgraded from 3.0.1 to 3.0.2 U1, and the first to give me problems.  The update seemed to install fine, but upon reboot, the server will not come back up in any mode.  I am no Linux guy, so I have no idea how to make changes to get it to boot, if it is possible to do so. This is the message I get:

root (hd0,0)

File system type is ext2fs, partition type 0x83

uppermem 277504

kernel --no-mem-option /vmlinuz-2.4.21-37.0.2.ELvmnix ro root=UUID=6f120080-93b7-4c4d-97e4-147b275cd892 mem=272M cpci=2: ;3: ;5: ;6: ;

Error 15: File Not Found

Any help would be greatly appreciated.
