Logged kernel messages when stopping kdm
I have this problem since a long time, but did not bother making a bug report
as it does not hang the machine; and a recent message on nouveau mailing list
reminding me of it. Here is what happens:
vt1 -> text console
vt7 -> kdm or logged kde session running
If I run /etc/init.d/kdm stop from the text console, I got the
PFIFO_CACHE_ERROR, if I do it from an X terminal in the kde session, no errors
happens.
Restarting the server from kdm login screen also does not produce errors.
Using gdm does not trigger the error in any case, so it's something specific to
kdm (from my pov). Also the fact I stop kdm from a different virtual console
may be important.
