From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Bottomley Subject: screen freeze with 5.2-rc6 Dell XPS-13 skylake i915 Date: Sat, 29 Jun 2019 11:56:52 -0700 Message-ID: <1561834612.3071.6.camel@HansenPartnership.com> Mime-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: intel-gfx@lists.freedesktop.org Cc: linux-kernel List-Id: intel-gfx@lists.freedesktop.org The symptoms are really weird: the screen image is locked in place. The machine is still functional and if I log in over the network I can do anything I like, including killing the X server and the display will never alter. It also seems that the system is accepting keyboard input because when it freezes I can cat information to a file (if the mouse was over an xterm) and verify over the network the file contents. Nothing unusual appears in dmesg when the lockup happens. The last kernel I booted successfully on the system was 5.0, so I'll try compiling 5.1 to narrow down the changes. James
