Yes, I'm quite sure. I ran it with anisotropy not set at all, and it ran for
over a half hour with no lock ups, but testing it with 1 caused it to lock up
within 5 minutes, and setting it above one (the highest setting, 16, in this
case) causes it to lock up.
Could it be a hardware bug that was fixed in rv250/280 series cards? Because I
have a true R200.
Additional notes: I originally came across this bug when playing with
DarkPlaces, a very popular Quake engine fork. It locked up every once in
awhile, and I couldn't understand why. So, one day, I decided to figure what
did it. I turned off all the GL extensions using command line flags, and slowly
turned each GL extension on until I found which one was crashing. The last on
the long list was the anisotropy extention, which would cause it to lock up.
Then, I built this little test to make sure it was that, and as you can see,
that is in fact whats doing it.
Even More Info: I'm currently on a Pentium 3 system, which uses a 82443BX/ZX/DX
(rev 03) AGP controller. My card identifies itself as a Radeon R200 QM. I'm
using Felix Kuehling's 20041002 cvs snapshot on 2.6.8.1.
