i guess it's a different problem from the PegasosI G3 but i could be wrong.

I'd like to receive  feedbacks and a working kernel config if someone is running with success linux-2.6.26.x on a Pmac B&W G3. This machine, altough obsolete, is still quite common.

The snapshot you posted doesn't have much information... there's no
obvious error for example in there...

What video driver are you trying to use ? Have you tried plain offb ?
(disabling whatever is the native driver for your video card, ie,
radeonfb or aty128fb or even atyfb, dunno what you have in there).

You can also try something like "udbg-immortal" on the kernel command
line see if that brings you more debug output.

Cheers,
Ben.

I know, I received from it from a user. It's where the kernel hangs.

Anyway, the last year, i received many install failures report from
cruxppc users. I hope it's only my fault building the bootkernel and
i'd like to receive a feedback from others distro developers for this
specific machine.

I always avoided to collect obsolete machines thus I don't have a B&W G3
but now i'm looking for one.

I'll try to receive more detailed info from that gentle user.

Thanks again for your kind support,

i asked for more tests and it seems  "udbg-immortal" maybe helped.
Here a new screenshot:
http://cruxppc.org/~acrux/DSC_0002_modified.jpg
and the bootkernel (config was attached in the previus mail) was
compiled with CONFIG_SMP=y

Does the problem happens if you compile it without CONFIG_SMP ?
