drm/dri/glxinfo on 6-current & xorg 6.8.2 with radeon 9200

[Randy Primeaux]

Hi,
I'm having trouble getting DRI direct rendering enabled.  I had it enabled
in October, however since then I've upgraded everything but my video
card.

The earliest point where I can find a failure report is in Xorg.0.log:
(EE) RADEON(0): [drm] Failed to map vertex/indirect buffers list

The only references I've been able to find (via Google) to the above
error is in the source files.
I'm wondering if it's DMA related? (just a shot in the dark)

Hardware is ASUS K8V-X, ATI Radeon 9200 5961 (AGP).
Software is FreeBSD 6-current, xorg 6.8.2, dri 6.2.1 (both from ports)

(for comparison)
http://www.cloudfactory.org/~randy/radeon/XFree86.0.log

In xorg.conf, I've tested with xorg drivers ati and radeon, and I've
got Section "Module", Load  "dri", Load  "glx", and Section "DRI",
Mode 0666

dmesg indicates:
agp0: <VIA 8385 host to PCI bridge> mem 0xe0000000-0xefffffff at

Section I think is relevant from Xorg.0.log:
(II) RADEON(0): X context handle = 0x00000001
(II) RADEON(0): [drm] installed DRM signal handler
(II) RADEON(0): [DRI] installation complete

(II) RADEON(0): Render acceleration enabled
(II) RADEON(0): Direct rendering disabled

I've fiddled with the BIOS a bit, and I moved my 3ware RAID and SCSI
cards over a slot to reduce IRQ sharing with the Radeon.  One thing I
haven't tried yet is compiling a new kernel without USB support, or
giving device.hints for USB to use different IRQ.  I've also
considered hinting at specific DMA, but haven't tried that yet.

I've tried the troubleshooting listed at
http://dri.freedesktop.org/wiki/DriTroubleshooting
and
