RE: [Linux-ia64] ia64_log_get error while booting

["Summers, Dow" <dsummers@verisign.com>]

I've been tracking this problem on my machine. I've worked out
that if I have a CD in the drive with the drive door closed when
the machine is powered on it will boot and run.  If there isn't
a CD in the drive and the drive door is closed when I boot the
machine the kerenl hangs in the MCA code.

I'm running Redhat 7.2 with a bios 109.

Well, it works now.  All I did was power cycle the machine.  I have no idea 
what could have been wrong.  I'll have to take a look at the BIOS level next

week.

Thanks for the help.
