Bug Description
I tested the Colony-4 live cd (ppc64) on an iMac G5.
Several times during the live cd start up, when the hardware is being detected
and configured, I get the error:
"error while running 'modprove -v sbp2'".
I assume that firewire in this model imac is not fully supported by the kernel?
Continuing through these errors, everything seems to work up until the live
gnome session starts.
The automatic login works, and it appears that the gnome desktop is starting up,
but then the system hangs with the mouse pointer frozen in place on a plain
brown background. At this point the system seems totally non-responsive:
doesn't respond to keyboard input (I can't switch to a text console), doesn't
respond to mouse movements (the pointer stays in one place only), and doesn't
respond to pings over the network. I've let the system sit in the "frozen"
state for up 10-15 min; it never recoverd.
There is a short time period when the gnome desktop is starting that the
keyboard and mouse still function (several seconds). If I quickly switch over
to a console, I see a series of errors (copied by hand, so I am missing some
information and may have a few things wrong):
hda: lost interrupt
hda: media error (bad sector)...
ide: failed op code was: unknown
end_request: I/O error...
Buffer I/O error indevice hda...
mpic_enable_irq timeout
ide-cd: cmd 0x3 timed out
These errors repeat over and over.
I did check the CDR I am using using the live-cd media check, and it reported
that my CDR is good. I also tried burning the ISO to 2 different disks and got
the same result.
This is a "first generation" iMac G5, with Nvidia FX5200 graphics adapter, USB
keyboard and mouse (no bluetooth). This system has an airport extreme card in
it, but it doesn't appear to be recognized (no surprise). The built in ethernet
is recognized, configured and activated.
The URL I included is a photo of the screen after the system freezes.
