new iBook and booting.

new iBook and booting.

[Carl Potter]

Hello Ben,

I thought I'd be slick and buy one of the new and improved 466MHz
iBooks (NOT Key Lime :) that Apple released a couple of weeks ago
....and put Linux on it.  Well I've studied and searched my hiney off
over the past week and for the life of me I just can't get YDL or
LinuxPPC 2K to boot when 'append = "video=atyXXX"' is used (I've tried
both atyfb and aty128fb).  I'm getting very close to being certain that
it's the newness of my iBook that's stopping me.  I have broken down and
decided to bother you with what might be a valid issue with the new
iBooks.  Here's some info on the factors involved:


Yaboot version 0.8

observed phenomenon when booting:  (using either 2.2.17pre20-ben3 or
Mike Palczewski's iBook kernel) with append="video=aty(anything)" on
either YDL 1.2 or LinuxPPC 2000:

This is the point where the screen freezes, leaving the above message
perfectly readable, yet the kernel continues to boot normally and mounts
the drive.  I then have to blind-type my username, password, and issue a
"shutdown -r now".

Any light you might shed on this would be very appreciated.  I think
Linux on PPC is great stuff and I thank you for making possible what we
can already do with it.

Take care,

Carl Potter

Please try to build a kernel with CONFIG_FBCON_FONTWIDTH8_ONLY enabled.
This fixed the problem for me (300Mhz,6GB iBook).

Though, admittedly, I don't see any reason in this.

PS: 433Mhz - I should have waited buying one ...

PPS: if I guessed wrong, here's the relevant part of my .config:
CONFIG_DUMMY_CONSOLE=y
CONFIG_FB_ATY=y
CONFIG_FB_OF=y
CONFIG_FBCON_CFB8=y
CONFIG_FBCON_CFB16=y
CONFIG_FBCON_CFB24=y
CONFIG_FBCON_CFB32=y
CONFIG_FBCON_FONTWIDTH8_ONLY=y
CONFIG_FBCON_FONTS=y
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y
CONFIG_FONT_SUN8x16=y
#
CONFIG_VT=y
CONFIG_VT_CONSOLE=y
