Savage IX/Thinkpad T20: Lockup with DMA

[Michael K. <ka...@ph...>]

Hello DRI developers,

on my ThinkPad T20, I experience Lockups with either type of DMA, be it
Vertex DMA or AGP texture access. With <Option "DmaMode" "None"> and
<Option "AGPMode" "2"> glxgears runs perfectly, as does glxinfo, whereas
ppracer locks up the system at start (supposedly because of using AGP
texturing). If I add <Option "BusType" "PCI">, everything works as
expected.

I am using:
  X Window System Version 6.9.0 (Debian 6.9.0.dfsg.1-2 20060106075605 David Nusinow <dnu...@de...>)
  common-20060124-linux.i386.tar.bz2
  savage-20060124-linux.i386.tar.bz2
  kernel 2.6.15-rc4 (is this a problem?)

Thanks for your work,
 Michael Karcher
