Re: G3 imac, networking, 2.6.12 kernel
I hate to keep pestering you folks with these, but...
I hit another glitch installing modern linux on archaic macs. (hey,
this one's _only_ 6 years old)
I just tried installing the stock 2.6.12 kernel on a G3 Imac (rev.
D, Paddington). The problem is:
a. the stock kernel doesn't have a driver for the network chip
compiled in.
b. the install procedures don't insmod the appropriate driver module
c. hotplug (testing/etch) package doesn't traverse the paddington
devices (macio bus).
d. It's not all that obvious which driver should be aliased to eth0.
I've poked around a bit and it seems that this is a common problem
with G3 macs where the devices are not visible to the pci bus.
And the answer is bmac. This problem has been around since at
least 2.6.7.
FWIW, the installation still fails with linux-image-2.6-15-1-powerpc
as neither hotplug nor udev can probe this particular machine.
I plan on filing a bug against linux-image-2.6.15-1-powerpc, along
with the script below for consideration as part of the postinst
process. Is that the ''correct'' package to post against?
I figure that this would be useful for OldWorld installations as well.
Are there other required modules that I missed?
Other comments?
#!/bin/bash
# Work around early NewWorld device probe limitations and explicitly
load modules
# required for certain well known configurations.
#
# 1. determine the required module(s):
case ` awk '/machine/{print $3}' /proc/cpuinfo` in
( iMac,1 ) modules=bmac;; # -- First generation iMacs.
( PowerBook,1 ) modules=bmac;; # --Lombard powerbook
( PowerMac,1 ) modules=bmac;; # --BW G3
#...and others as necessary.
esac;
# 2. direct the kernel to load the module(s)
for mod in $modules; do
if ( ! grep $mod /etc/modules /dev/null ); then
echo $mod /etc/modules;
echo module $module added to /etc/modules;
fi;
done;
# 3. other notification of config changes as appropriate (e.g. email
to root)

I would think the correct fix would be to update hotplug and friends to know about macio. There was a patch floating around to do just that. I agree and wish it would happen. But that patch has been floating around for 6-8 months. How much longer should folks wait? Given that hotplug/udev is _new_ functionality with 2.6; whereas 2.4's _existing_ network functionality is _broken_ by upgrading the kernel; it seems to me that a workaround is in order until the h/w probe is patched (if ever). Whatever workaround is untilmately ''accepted'' by the maintainer doesn't need to modify /etc/modules directly. At the very least it should inform the (potentially naive) installer of known fixes to known problems so they can get up and running pronto. I also get the sense that since the affected machines are at least 5 years old, that as time passes, there'll be less and less incentive to propagate the patch. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

It's not all that obvious which driver should be aliased to eth0. I've poked around a bit and it seems that this is a common problem with G3 macs where the devices are not visible to the pci bus. So, what's the ''naive'' user to do - is there a powerpc package with the macio.rc patches for hotplug? (see http://www.ussg.iu.edu/hypermail/linux/kernel/ 0503.0/0192.html) N.B. I'm assuming the kernel patches are in 2.6.12. The network device does show up in /sys. so please correct me if I'm wrong.) - if not, is there a recipe for loading the drivers for the divers macio devices. - should a bug be filed against linux-kernel-2.6.12-powerpc? I ask because 2.4.18 installed just fine.
