A loop? Or just a hang?

Judging only by the stack trace, it looks like your application is
waiting for a reply that never comes. There are a variety of bugs that
can cause that. The sequence number (30) looks reasonable for
application startup, which rules out one or two things.

For the rest, if the Intel/Mesa folks don't have an answer, it would
help if you could get a trace of the X wire protocol using something
like Wireshark.
