wide range of displays. He's running 4.4.0-62.83 and notes this is definitely a regression as it was working previously.

Do we know the last working kernel, so we can "bisect"?

This issue could not reproduce with an AOC E2460SW Widescreen (24" 1920 x 1080 16:9).

I tried to reproduce by the following steps:

1. Enabled the proposed pocket, and updated the system via GUI updater.
2. After updating the system, reboot.
3. Plug-in the aforementioned monitor in the HDMI jack of the XPS15.
4. Check dmesg and /var/log/syslog. The panic message could not be found in both of them. The screen of external HDMI monitor and the internal monitor looks good as well.
5. Suspend the system by the desktop indicator.
6. After the system resumed, repeated the step3. I got the same result as the step4.

I took the xps15 from tai. The kernel is already upgraded to 4.4.0-62.
I tested it with PHILIPS 288PL6 4K monitor and cannot reproduce the issue. Connected the monitor via HDMI and Type-C (to HDMI) ports and both works well. All display modes are available. Checked dmesg and /var/log/syslog, there is no similar warning or kernel panics messages.

I built the attached patch and put the binaries at [1].

It would be nice to have someone test it before we push it for review and maybe respin.

I had Mark test a kernel which jsalisbury built that reverted the following commits:

c173e45ac693 UBUNTU: SAUCE: i915_bpo: Validate mode against max. link data rate for DP MST

Mark's feedback is as follows:

"OK. Before I installed the kernel I plugged in the switched-off
projector, and saw this:

So, those patches do not need to be reverted. The actual panic was likely something other than i915_bpo related.
