Hello,

I have a kernel page fault when I start X with the use of DRM. kernel
log is:


[drm:pid14460:drm_open] open_count = 0

I have a radeon M6 (RV100) PCI detected at boot time:

radeondrm0 at vga0
info: [drm] ATI Radeon LY RV100 Mobility M6 (unit 0)
[drm:pid0:drm_load]
[drm:pid0:radeon_driver_load] PCI card detected
[drm:pid0:drm_ctxbitmap_next] drm_ctxbitmap_next bit : 0
[drm:pid0:drm_ctxbitmap_init] drm_ctxbitmap_init : 0
info: [drm] Initialized radeon 1.25.0 20060524


My cpu is a transmeta crusoe TM5800 who is lacking MTRR. Do you think
this is where the problem come from ? Can we disable the use of MTRR on
the radeon drm driver ?

(I use netbsd-current upated yesterday, modular X.org 7.2 from
x11/xf86-video-ati and the wip/mesa-dri package)

Thank you for your help!

Best regards,
jym
