Bug#616389: xserver-xorg-video-radeon: Crashes when closing graphical VT ("(EE) RADEON(0): failed to set mode: Permission denied")

[Thue Janus Kristensen <thuejk@gmail.com>]

I just tried, and with a gdb attached to both processes, there is no crash. I had to continue over some SIGPIPE etc, but I assume that is normal.

So I assume that the problem is some kind of race condition? As I said, it is 100% reproducible until I tried it in gdb :).

Would be interesting if one of you guys could (from a remote login)
attach gdb to both X servers and check that the second X server calls
drmDropMaster() or dies before the first X server calls drmSetMaster().
