I've got a Lenovo T410 w/ an external display (DisplayPort<->HDMI). After
upgrading from a 4.2 kernel to a 4.3, I started hitting an issue where
the display thinks it has lost input for a few moments. Oddly, it
usually happens when I start typing in a terminal after a short period
of inactivity.
I see no OS-side symptoms - there are no new messages in dmesg/syslog/Xorg
log, etc. I reproduced with latest Linus master (@ 3e1e21c7b), and then
bisected down to the following commit:
commit 7221fc333dbe1743a3dff155b03527fda90d4ec1
