Description of problem:
50% of the way through the ``Performing post install configuration...'' this
cpu 0x1: Vector: 200 (Machine Check) at [c0000000077cb7d0]

paca = 0xc00000000046e000
pid = 10855, comm = modprobe
enter ? for help
[but the m/c's actually wedged]
[I'm wondering if it is installed enoug to boot?]
Disabling "printer services" (in the hope that it would stop cups/this print
stuff crashing the m/c didn't work).
- proceed for a normal install all the way through to the point where the RPMs
have started installing
- wait until you've seen the kernel[s](1) unpacked (if the install get's past
50% then it's likely installed anyway) but _before_ the unpacking of all RPMs
- Switch to the alternate screen with the shell prompt (<alt> <F2> from memory)
- (going from memory)
Remove the file:
(of course you can switch to the F2 screen earlier and just keep repeating the
delete - but that might miss something on the main screen).
- allow the install to finish as normal
(1) You might notice a 32-bit smp kernel being installed. Ignore that it's a
known bug (bug #149618). The 64-bit kernel is SMP.
A G4 _occasionally_ either: hangs during the install; or hangs when starting
cups during a normal boot; for what appears to be the same reason.
Fixed in newer kernels by removing the PC parallel port driver which was causing
