After a while (I'm not sure how long) using nouveau, something happens which causes all of these symptoms to begin:
1. cursor movments become jerky
2. moving cursor from one screen to another leaves a copy of the cursor on the first screen
3. syslog shows many lines of "nouveau 0000:01:00.0: no space while hiding cursor"
4. switching to a text VT 'hangs' the display (showing the X screen still) and switching back 'unhangs' display (while on a text VT, though you can't see anything, you can do things 'blindly')
5. restarting X leaves the screen 'hung' with no ability to SysRq+REISUB (keyboard is fully locked up)
A while after the above happens, the entire system will become unresponsive (though background process like RAID resync or torrent continue), and the keyboard doesn't work at all. The only thing that works is moving the mouse cursor.
Reproducible: Always
Steps to Reproduce:
1. use a computer with the nouveau driver for 'a while'
Actual Results:
Please see 'description'.
Expected Results:
No loss of stability over time.
