One of my RS/6000 (44P Model 170) machines is stuck in a reboot loop. Nothing was changed. I arrived in the morning to start up the machine and it arrives to the IBM bootup screen and the last thing displayed is:
Boot device /pci@fef00000/scsi@c/sd@4,0
Closing stdin and stout....
Then it reboots. The last things on the error display is: E051
Does anyone know what's wrong?
