r128 + agpgart + APM suspend = death

r128 + agpgart + APM suspend = death

[Erik Andersen]

I have a Dell Latitude C800 laptop.  It works just great and
I can use agpgart + r128 + XFree86 4.0.1 to get nice full 
screen 3D.  tuxracer looks nice.

But if I suspend my laptop when the agpgart module is loaded
is seems to suspend just fine, but will not resume....  Just
a black screen (of death).   If I ensure that the agpgart and
r128 modules are not loaded (by commenting out the 'Load "dri"'
line in /etc/X11/XF86Config-4, then killing X and unloading 
the modules) then I can suspend.

Anyone else seeing similar problems with APM + agpgart?
The problem has has been the same with all the 2.4.x kernels
I've tried it on, though I am running 2.4.12-ac6 at the moment.

Same for me with an Inspiron 8000. I haven't had much time to look
carefully at it, though.

One more bit of data.  XFree86 reports that my system has a:
    (--) PCI:*(1:0:0) ATI Rage 128 Mobility MF rev 0, Mem @ 0xe8000000/26, 0xfcffc000/14, I/O @ 0xcc00/8

A few friends of mine have similar Dell laptops with the same set of kernel
modules loaded -- and theirs do not choke on APM suspend.  But their systems 
report a slightly different r128 model: 
    (--) PCI:*(1:0:0) ATI Rage 128 Mobility LF rev 2, Mem @ 0xf8000000/26, 0xf4100000/14, I/O @ 0x2000/8

Hi Erik,

my machine prints the same message, but your mail prompted me to
update my bios (from A10 to A17), and now I can suspend and resume w/
agpgart loaded. Using 2.4.12-ac5 and XFree 4.1.0

HTH,
