I'm sorry that I couldn't use the normal kernel bug-reporting process, but since we're hitting this problem in the installer, I'm not sure what else we can do. I also apologize that I don't have any more info, since it's after Midnight local time, but I wanted to make sure I got this information through to you ASAP. At this point, we're probably going to move forward with the 16.04.4 Server installer for now, but we do have an identical C6420 node (in a different chassis), and we will probably be able to use that for testing for at least a little while! For example, we were thinking of trying the 16.04 HWE kernel, as an additional data point. So, please let us know what additional information you would like, and what else we can try.

We are experiencing a soft lockup when booting the Bionic Server installer amd64 ISO (kernel 4.15.0-20). The installer seems to hang on boot: After GRUB, nothing ever appears on the display, and we only managed to get kernel logs through Serial-Over-LAN. The 16.04.4 Server installer ISO (kernel 4.4.0-16) does not seem to have this problem. Our hardware is a Dell C6420. The C6420 is one node in a four-node, 2 U chassis (the C6400 chassis). The node's hardware is two Intel Xeon Gold 6134 CPUs (8 cores @ 3.2 GHz/core). RAM is 96 GB, as twelve 8 GB DIMMs. We have tested with Hyperthreading on and off, and with UFEI and BIOS boot modes, and we get the same results in both cases. Right now, we have Hyperthreading on, and we are booting in UEFI mode. If you need us to change that for testing, let us know!
