It would be good to see a full backtrace from gdb, but this doesn't look
directly related to the driver.

Attempting to get backtrace from gdb by ssh from other machine
is still unsuccessfull. During Xorg freeze on remote host, gdb screen on main machine says nothing.
On the screen still:
-------------------
(gdb) continue
Continuing.
------------------
As you can see, no info about receiving signal SIGSEGV.
I would appreciate any suggestions how to get a miningfull backtrace of Xorg
(maybe any trick).
But I got somthing like this, when instead of freezing Xorg disappeared and screen switched
to this:
