Bug detailed description:
-------------------------
startx, run "chvt 1" to switch to the text console , then we can not bring back to X. when run "chvt 7", it still stays at the console. and X seems like hanging.
we fail to kill it using "pkill -9 X", the only thing we can do is to reboot.and dmesg shows nothing wrong. I think it is a regression, it worked before 1 weeks. 
Reproduce steps:
----------------
1.xinit&
2.chvt 1
3.chvt 7

Works for me with bits from today; can you try again?  And capture the dmesg along with a backtrace of X after you try to switch back?
Comment 3 liuhaien 2009-03-12 19:26:41 UTC 
it works against the latest for-airlied kernel:
