Hi,
Welcome to the kpm dump world. We've been having this problem for a while and
haven't had any success in resolving it. From tests and data we've gathered, we
are pretty convinced that this is due to texture memory oversubscribing and
multiple graphics contexts running concurrently.
The problem is a real nightmare since there is no real way to trace the problem
codewise and due to the fact that, in our application, it can take up to 18h00
to reproduce.
The final outcome of this is a kpm dump file that you will find in:
/var/adm/crash/diags/gfx/IR/
kpm files can be identified with date and time. Looking at your
kpm_dddddd_tttttt.rslt, you should notice that all your texture managers are
all hosed.
By the way, kpm stands for Kona Post Mortem :)
Please keep me updated if you have any more insight or info on this. I will
keep you posted likewise.
