Trouble with 2.6.0-test1 on ibook2

Trouble with 2.6.0-test1 on ibook2

[Ryan Boder]

I'm trying to boot 2.6.0-test1 on my ibook2. I compiled a kernel and it
begins to boot but hangs immediately after the line

openpic: exit

is printed. Or at least seems to hang as the screen stops showing anything
else and just leaves the messages up to that point forever. It also
corrupted my file system so I'm reinstalling now.

Has anyone been running the devel kernel on an ibook2? Can anyone give me
pointers on how to debug or work around this problem when I finish
reinstalling?

What graphics chip does the machine have, and have you built OFfb into
the kernel? For me, radeonfb hasn't been working with recent 2.5
kernels, in fact there's been no trace whatsoever of it in the kernel
output, as if it wasn't there. I wonder if it's related to the PCI code;
with a 2.4 kernel, I get a lot of PCI related output, like

PCI: Probing PCI hardware
Scanning bus 00
Found 00:58 [106b/002d] 000600 00
Found 00:80 [1002/4c66] 000300 00
Fixup res 1 (101) of dev 00:10.0: 400 -> 802400
Fixups for bus 00
Bus scan for 00 returning with max=00
Scanning bus 10

[ more PCI probing stuff ]

PCI:24:0e.0: Resource 0: f5000000-f5000fff (f=200), vd: 11c1, dev: 5811
Linux NET4.0 for Linux 2.4

whereas with a 2.5 kernel just this:

PCI: Probing PCI hardware
Can't get bus-range for /pci@f2000000/cardbus@1a
BIO: pool of 256 setup, 14Kb (56 bytes/bio)

But then maybe the code in question has just been made less verbose?

Rage Mobility M3 AGP 2x (rev 02).

Yes, I did. I'll try again without that as soon as my iso finished
downloading. I figure I might as well move to YDL 3.0 while I'm
reinstalling.

Thanks for the advice,

Well, OFfb comes up fine here.

I got it working by using the pmac defconfig and just modifying that. I
suppose a smarter person would have done that in the first place instead of
just doing the config from scratch.

I'm still having an issue with the devel kernel and XFree86, but the airport
driver is working and that's what I'm interested in working on so I guess
I'm OK.

Thanks for the help,
