Hi Jeff, sorry - I tried to be as accurate as possible. In or out of fstab - I can only boot in the older kernel, 4.4.0-62 otherwise it freezes on boot.
As per instructions on bug reporting, I ran lsb_release -rd, which printed 18.04.3 LTS on the first line, Release 18.04 on the second line. Seth on IRC told me to run a command which I did that then put all the debug info on this ticket. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1854881 Title: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel Status in linux package in Ubuntu: Confirmed Bug description: Hi All, Host Server - Dell PowerEdge R630, Dual Xeon E5-2650 v4, 768GB Memory, ESX 6.5.0 I created a VM with 1vCPU, 2GB Memory, 16GB Hard drive. I installed Ubuntu Server 16.04.2 (latest ISO I had on hand), installed fine. I then ran apt-get update, apt-get upgrade... upgrade failed as repos were out of date. I then ran do-distribution-upgrade, ran through everything and it appears to work. --I don't want to mislead anyone - I can't remember if I rebooted or not at this point. After this, I setup an Iscsi initiator to an external target, added to fstab, formatted and confirmed all working. I then rebooted, and... nothing! No ping, no ssh or anything... Control + Alt + Del did not work, looked like it had frozen. The last line was starting SSH, but the previous line was the Iscsi initiator. At this point, I figured network is down and ISCSI is hanging as it can't connect/maybe I messed up the ISCSI mount. I then went to GRUB and did advanced, I did the recovery console for kernel 4.15.0-72 generic which lead to a kernel panic: https://snipboard.io/YCOZwv.jpg I then went through the options again and selected 4.4.0-62 generic, and it booted fine, and after about 2 seconds at the recovery menu, further ISCSI related text came up: https://snipboard.io/ALZcsF.jpg I went to the shell as root, deleted the line from fstab, and rebooted, but, it hang again at the same point. I then went to advanced, booted normally to 4.4.0-62 generic, and, it went through without any issue what so ever. Messing around with kernels puts me out of my depth... happy to give further info or do more diagnostics if required, however, due to it working in a different kernel and nothing out of the ordinary - I believe this to be a bug.
