[Kernel-packages] [Bug 1812758] Re: Boot failure on Dell Precision 5820 with Intel Xeon W-2123 CPU
I had a similar issue with an existing Ubuntu 16.04 LTS install on my Dell Precision 5820 tower that has booted without issue for 2 years. After updating the BIOS via the Ubuntu Software Center (to 1.13.0), my computer gave only a black screen. After clearing the BIOS, CMOS and NVRAM by removing the CMOS battery, it would only boot to BusyBox. BusyBox gave me a "ALERT! UUID=*** does not exist. Dropping to a shell" error. My OS is installed on a NVMe PCIe SSD boot drive, and I have a single SATA file drive. Setting the SATA Operation from to "AHCI" and Disabling the "Intel VMD Technology" under System Configuration in the BIOS seems to have solved the issue for me as well.

These machines are lease refreshes. I created a UEFI image of 16.04.5, selected "Install Ubuntu" and then starts throwing a bunch of error messages stating [33.192238] nouveau :05:00.0: DRM: base-0: timeout repeating over and over again. It never gets past this. I tried the suggestions of adding "nomodeset" in grub when I'm booting. It progresses a little further but hangs at "failed to start Ubuntu Installation Service, please run journalctl to see what failed". I can't see what failed as I can't get a prompt since nothing is installed. I don't know where to go debug from here. My computer boots to a black screen, what options do I have to fix it?

Unfortunately, 16.04.1 didn't support the integrated Intel i219-LM network card. I tried 16.04.2, 16.04.3, 16.04.4 and they all exhibit the same behavior as 16.04.5 with the video. Just as a test, I installed 16.04.1, installed broadcom NIC (which was successfully detected), and upgraded from 16.04.1 --> 16.04.5 with apt-get and had no video issues after reboot (I didn't install the video drivers), in addition, after it was upgraded to 16.04.5 the Intel 219-LM drivers were added and would work. I have a workaround, but it's REALLY annoying. The kicker in this is that the Dell Precision 5810 worked 100% correctly. Put the USB boot drive in, select the drive in UEFI to boot and everything works out of the box. I'm working on gathering more logs of this issue and testing different kernel versions.

It does not seem to correspond to a particular program or action. When that happens, the screen goes to black, then returns after a few seconds. At that point, the time on the clock is static and indicates that the screen is frozen, but audio continues to play for 30 seconds to a minute. The keyboard and mouse do not affect what's being displayed, but I can Alt - SysRq - REISUB to restart. Every time (7 crashes and counting), /var/log/kern.log indicates that kernel: [353692.378886] radeon :03:00.0: ring 0 stalled for more than 10280msec kernel: [353692.378896] radeon
