Thanks Karanbir,
 Very generic, basic off the shelf workstation stuff, both have been running 
CentOS for over a year without problems and other machines that are OK have 
very similar specs all are AMD 64:

AMD Athlon(tm) 64 X2 Dual Core Processor 6400+
4Gb ram

AMD Athlon(tm) 64 X2 Dual Core Processor 4200+
2 Gb ram

 This is very repeatable and nothing seems to be written to /var/log/messages 
during failed boots, is this normal?

Cheers,
Colin.
