Description Gianpaolo Mazzoni 2002-08-09 18:31:02 UTC
In the new 1.4 iso there is a problem getting the cdrom/dvd device.
After booting from the iso image, the /dev/cdroms/ directory is empty and there isn't any 
device hde (in the stable 1.2 iso the dvd is identyfied by the hde device and work 
properly). In the boot message I can't find any message about the dvd of my PowerBook 
G3 Pismo.

Comment 2 Mark Guertin 2002-08-11 19:12:06 UTC
Hmmm, do you have a kernel .config that you use for that machine around?  i
would like to see if if you could upload it to make necessary changes to the
kernel config for ISO.
Comment 3 Gianpaolo Mazzoni 2002-08-12 02:09:35 UTC
I haven't yet a kernel .config to upload, because I'm trying to install the 1.2 
However, with the 1.2 boot cd the LG DVD is reported without problem; dmes 
show "hde: LG DVD etc.."

I'm installing the 1.2-r1 release, probably today I can post a working .config 
file for my PoweBook.
Comment 4 Mark Guertin 2002-08-12 15:51:18 UTC
I have an idea why this may not be working, try adding this append when you boot
with yaboot:


This may be the problem, as by default I am not sure that there is a /dev/hde
without devfs and it's the only thing I can think of that would be different
from old kernel to new one.

1.2 dmesg

This is the dmesg output from gentoo 1.2 boot cd.
Only in this release, the cdrom/dvd is present.

1.2 r1 dmesg

This is the dmesg output from gentoo 1.2 r1 boot cd.
With this version and with the 1.4 pre-release the cdrom's device is not
Comment 7 Gianpaolo Mazzoni 2002-08-12 17:05:44 UTC
Hi Mark, I created two attachment with the output of dmesg from boot cd.
In the working release (1.2 kernel r3) is present the cdrom's device linked to a
scsi channel (I don't understand if there's an emulation of ide or an emulation
of scsi; excuse me for my poor knowledge and english).
In the "buggy" releases (1.2 r1 & 1.4 >> kernel r6) there's a problem with a
scsi module during startup; maybe this is the problem (without scsi the cdrom
isn't emulated)?!?

Ps: because I'm not able yet, to build a booting kernel, I'm not able to append
the option in yaboot. What are the full comand to pass at the yaboot prompt with
the gentoo boot cd?
Comment 8 Mark Guertin 2002-08-12 17:26:34 UTC
for the options just do this at yaboot prompt: 
boot devfs=mount 
(any append option in yaboot can also be typed on tha yaboot command line) :)

working kernel config

Probably the bug is solved ;-)
In the working config attached, the only difference show comparing the
"original" config is with the "Power management for Powerbook" option; like
reported by the help, this options enable also the Media bay, and so the

Bye, GianBeOS.
Comment 10 Mark Guertin 2002-08-13 09:56:02 UTC
# CONFIG_PMAC_PBOOK is not set

Yep you are correct, that comes from our ISO kernel config.  I will get this
looked after immediately :)
Comment 11 Kevyn Shortell (RETIRED) gentoo-dev 2002-08-25 19:20:46 UTC
looked at. Fixed. Thank you for the bug report, would have never even noticed.
All my gentoo ppc boxes are core99 machines, which don't have media bays. lol. 

Comment 12 Kevyn Shortell (RETIRED) gentoo-dev 2002-08-27 01:41:29 UTC
Tested new 1.4 ISO kernel for PPC on a Powerbook G3 '99, media bay device 
detected and assigned. Will post new kernel for workaround until final 1.4 ISO 

Closing bug.
