Subject: BUG: 2.2.0-pre2 on 5500 (and maybe 6500)
Date: Fri, 01 Jan 1999 15:29:25 +0100 [thread overview]
Message-ID: <368CDBC4.366C@post.uni-bielefeld.de> (raw)
Hi !
This bugreport applies to a PMac 5500/225, and maybe a 6500, because
they share a common motherboard.
I'm booting 2.2.0-pre2 kernel with BootX.
ftp://ftp.linuxppc.org/linuxppc/linuxppc-pre-R5/RedHat.installer/vmlinux-2.2.0-pre2
No-video problem:
First I'm booting with the "no video" box checked. I get a much too dark
picture, I can only see a few shades from the logo. I can't see the
login prompt. The last kernel I checked (2.1.127) didn't have this
problem.
Possible bug: palette not initialised.
Then I tried without the "no video" box. Now I get no video at all. This
is a problem I have since the first Kernel I've seen (2.1.24). Is there
a problem with my video-chip ? I've got an ATI chip, ATY264GT-B.
Audio problem:
You'll see in the kernel messages that there is an error during the
initialisation of AWACS. Now audio seems to be limited to 8kHz/mono.
BTW: Where has this "woop" sound gone to ? I prefer it much over a
simple beep...
I'll try test-kernels, but please reduce them of all options (network,
filesystem) that are not needed to test video/audio.
I've got the usual dmesg and a dump of the OF-tree. Anybody interested
in seeing this ? It's around 3k.
Jens
P.S.: Patch ? I'd like to, but I have not much information about the
hardware. What about starting a project to document all devices in a Mac
?
P.P.S: BootX vs. OF: I'm normally booting with OF, but to test kernels
I'm using BootX. It's a very nice program...
