Description of problem: 50% of the way through the ``Performing post install configuration...'' this popped up: cpu 0x1: Vector: 200 (Machine Check) at [c0000000077cb7d0] pc: d000000000276a98: .parport_ECR_present+0x1f8/0x470 [parport_pc] lr: d0000000002780f8: .parport_pc_probe_port+0x5b8/0x700 [parport_pc] sp: c0000000077cba50 msr: 9000000000109032 current = 0xc00000000a09d810 paca = 0xc00000000046e000 pid = 10855, comm = modprobe enter ? for help 1:mon> [but the m/c's actually wedged] [I'm wondering if it is installed enoug to boot?]
Additional note. Disabling "printer services" (in the hope that it would stop cups/this print stuff crashing the m/c didn't work).
Workaround: - 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 has finished - Switch to the alternate screen with the shell prompt (<alt> <F2> from memory) - (going from memory) Remove the file: /mnt/sysimage/lib/modules/`uname -r`/kernel/drivers/parport/parport_pc.ko or /mnt/sysimage/lib/modules/*/kernel/drivers/parport/parport_pc.ko (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 the crash.
