Also tried gdb from ports tree. It's output pretty similar , except legacy gdb outputs ~150 frames whereas gdb from ports 12. >> From the evidence sent to me in private, it seems that the gem page fault >> handler might be responsible for the problem.

As I already mentioned, unfortunately there is no exact STR how to reproduce the issue (or at least I don't know how to reproduce it: whenever I tried to do the same I had been doing when Xorg crashed everything just worked). So it usually takes some time to obtain core. However after 8.3 was applied no cores over here. Bad news: Xorg started to freeze (again: I don't know how to reproduce it since it happens randomly and not so often (2 times during the last 24 hours)). It looks like bellow: - display remains intact, neither keyboard not mice events are recognized and there is no way to get it back working but reboot the machine (earlier after crashes I was able "blindly" switch to another vt, login and restart xdm). - machine is accessible via network, so I can login, though it is impossible to kill Xorg process (tried 3, 6, 9). It is also impossible to attach to Xorg process. gdb hangs right after it prints it's banner) I've collected ktrdump output. It is quite large (~500k after compression), so I'll send it to you off-list. Thanks! -- WBR, Andrey Kosachenko
