Hello,
Debian "Squeeze" Testing just switched from UMS to KMS r300
initialization on my system. As some may remember, DRI wasn't
available with UMS initialization due to a commit during the kernel
2.6.30 development cycle (all the story there:
http://marc.info/?l=linux-ia64&m=126382946814671&w=2). Now with KMS
initialization, glxinfo happily reports that DRI is enabled, but I
frankly doubt about this. Indeed, I'm recording some confusing
error/warning messages (e.g. [TTM] AGP Bind memory failed., [TTM]
Couldn't bind backend. and [drm] Forcing AGP to PCI mode) and a crash
in dmesg:

This is with current Debian "Squeeze" Testing kernel 2.6.32, but I'm
getting similar results with a freshly recompiled 2.6.34 kernel.
First, is this kernel related (in short, am I in the right mailing-list)?
Then, if kernel related, it's noteworthy that the hp_agp.ko module is
no more loaded into memory (although it's still listed in /etc/modules
and from the dmesg log above, agpgart seems to correctly identify HP
ZX1 HWP0003 AGP chipset), whereas UMS was loading it. Is this
expected?

Emeric
