 Is/was there a panic message on the console? Ordinarily the system
 won't reboot upon pressing enter like that unless there's been an
 explicit panic.
 
 If you can, please try 5.1 -- I think at least one source of "generic
 HBA error" problems has been fixed.

 Probably won't do us much good, but if you find it please send the
 information in.
