Hello Michael,
I managed to compile and start a 2.4.22 kernel (with aty... patch
applied).
=> executes some atyfb specific code (see below)
atyfb: using auxiliary register aperture
atyfb: 3D RAGE (XL pCI-33MHz) [0x4752 rev 0x27] 4M DRAM, 29.498928 MHz
XTAL, 23K
Console: switching to colour frame buffer device 80x25
fb0: ATY Mach64 frame buffer device on PCI
Dummy keyboard driver installed.
=> the output varies from either
- my monitor stating "no signal"
- to "input not supported"
=> is there any further way to debug this behaviour?
---
Unfortunately the kernel later on reproducibly crashes at
NET4: Linux TCP/IP 1.fos: ICMP, UDP,�CP,�GMP
IP: rhats, CPreinti Pain sockets 1.0/SMP for Linux NET4.0.
Unable to handle kernel paging request at virtual address fffff000,�pc
== 8028 0
Oops in fault.c::do_page_fault, line 206:
$0 : 00000000
=> We can hopefully solve this by agreeing on a common (proven to work)
test basis => see below.
------------------------
Can we do a few things to coordinate further work:
1. Are we using the same miniPCI ATI Rage XL? Mine is an Micro Star MS
9513 and states
[root@meshcube02 /]# lspci -vv
0000:00:03.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev

2. Can we please put
- a hint on what kernel source to use (e.g. tag for retrieval
from mips-linux CVS) and any necessary further
modifications
- a .config file for the kernel
on the Wiki?
Looking forward to seeing something on my monitor! :-)
regards
Ralf
