Bug#892517: linux: swiotlb coherent allocation failed

Hi,
this is happening to me too, with nouveau drivers, and it starts for
example with a huge file transfer over LAN.
Btw as i can read on lklm.org and some other places on the net, it
seems the proposed patch is just addressing log spamming and
suppressing all those dmesg lines, while in my case i can say that
this issue is affecting user interaction as well, since the graphics
interface is stuttering and looks very unresponsive while the problem
is in progress. It's not just a matter of logs noise.
For example my interface was really laggish few minutes ago, and i
tryed to kill a firefox instance running inside a Xephyr display which
i discovered not responding anymore. The error messages suddenly
stopped filling the logs, and the general user interaction came back
as fluid as it should normally be. So i don't know if it's just me,
but in my case there is an impact on the graphical performance.

Thank you.
