Bug#942563: Workaround for older chips
This workaround from the Debian iwlwifi wiki seems to have fixed the problem on my WiFi 5100 Link adapter: Troubleshooting Slow WiFi problems when using Bluetooth Some devices like the 6235 do include a Bluetooth device in the same card, which may lead into radio conflict. Newer devices (7200 and up) try to solve them intelligently, but it is not the case of older ones. If your WiFi is slow when using Bluetooth, try adding the following to /etc/modprobe.d/iwlwifi.conf and reboot: - options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8 https://wiki.debian.org/iwlwifi
Bug#942563: Any progress on getting a fix for this?

Bug#948257: Is there a fix coming down the pike?
Can we expect a fix soon in whatever package causes the console spam? It's a rude awakening to get hit by these messages first thing in the morning when doing maintenance.
Bug#909260: Retry coming
I will be retrying the 'make deb-pkg' build with kernel version 5 source in the next few days. I will report back later.
Bug#909260: Utilities used
Using gcc and binutils

Just installed it from testing distribution and no black screen, modeset worked fine.
Bug#914495: Bug appearing on Intel GM965
I incorrectly stated there was no problem on one of my Debian machines with video adapter Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c). There is black screen and lightdm failed to start after this: BUG: unable to handle kernel NULL pointer dereference at 0004 [Tue Dec 4 12:30:21 2018] *pdpt = 36555001 *pde = [Tue Dec 4 12:30:21 2018] Oops: [#1] SMP [Tue Dec 4 12:30:21 2018] CPU: 0 PID: 316 Comm: systemd-udevd Not tainted 4.18.0-3-686-pae #1 Debian 4.18.20-2 [Tue Dec 4 12:30:21 2018] Hardware name: Dell Inc.

Bug#914495: More evidence that the gen4 adapter commit is at fault
I have 3 Debian machines in the lab, and two booted 4.18.3 fine. One has a Radeon GPU, the other is an Intel GM965. The one that gave me the black screen at boot is: lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Bug#914495: nomodeset enabled boot
But the graphics mode is low res (1280x768). Also, 'nomodeset' is no longer documented in the kernel parameters doc ( https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt).
