[13:21] <PaulePanter> Hi. A user has a Dell Latitude 5500 with Dell’s pre-installed Ubuntu 18.04.
[13:21] <PaulePanter> All packages are updated.
[13:21] <PaulePanter> Unfortunately, it doesn’t boot anymore. It just hangs after GRUB.
[13:22] <PaulePanter> Trying to debug it, it turns out that `maxcpus=1` fixes it a little bit. The first time it still fails, but then forcefully powering it off, the second attempt often works.
[13:22] <PaulePanter> What channel would be best to report that to? What Launchpad component is the right place?
[13:23] <PaulePanter> Unfortunately, I do not get the console messages on the screen (unless I remove the initrd line in GRUB), and there is no serial console.
[13:28] <PaulePanter> Sounds similar to https://www.dell.com/community/Latitude/Latitude-5400-boot-fail-after-BIOS-update-to-1-6-3/td-p/7442753
[13:28] <PaulePanter> but the firmware was updated in February, and the disk firmware on March 3rd.
[13:28] <PaulePanter> And some boots after that worked.
[13:29] <PaulePanter> Any suggestions?
[13:37]  * PaulePanter also wants to note, that the Dell TB16 docking station also does not work well under GNU/Linux (Ubuntu, Debian, …).
[16:54] <PaulePanter> After the battery went out of juice, starting the system again, the problem disappeared.
[16:54] <PaulePanter> So something might be broken in the initramfs?
