[ 1580.616767] [TTM] Buffer eviction failed Once this happens, the mouse cursor moves, but the desktop is otherwise unresponsive. I can't use ctrl-alt-Fn to get to a text console.

It seems like it always occurs when I'm interacting with a web page in either firefox or chromium, but that might just be because that's most of the time. -- Package-specific info: ** Version: Linux version 4.3.0-1-amd64 (debian-kernel@lists.debian.org) (gcc version 5.3.1 20151207 (Debian 5.3.1-3) ) #1 SMP Debian 4.3.3-2 (2015-12-17) ** Command line: BOOT_IMAGE=/boot/vmlinuz-4.3.0-1-amd64 root=UUID=1bd202e7-8d8c-4170-8388-abddc49cd075 ro quiet ** Not tainted ** Kernel log: ...
