With Kernel 4 I get the expected behavior of a swapping system. It lags and is hard to use in times. But it's not completely locked for several minutes. Does this proof that it's NOT Freedesktop/xorg related? How long has the GUI to hang until I should get the above error message in the syslog? Hello Alexander I had a problem with VirtualBox as well. My host always crashed because of kswapd running amok after a few minutes of running the VM. My solution was to add a small swap space (1 GB). Since then the PC is suffering from the GUI lock mentioned here. so, do you have SWAP? What happens with the VM if you remove all swap space of the host? did you ever notice kswapd taking 100% cpu? what do you mean with GPU passthrough? is this VMware specific? kind regards Jan</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
