Not sure if you're still experiencing this bug, but just in case you or someone else stumbles over this, here is my solution. I just bought the same laptop and had a similar issue. When trying to wake up from suspend, the system freezes with lots of filesystem errors. After a few very annoying hours of googling and trying to trace the problem I found a solution in this thread. Apparently some SSDs in Dell laptops don't behave correctly in combination with ASPM, resulting in the system not being able to properly wake up the SSD after suspend. Hence the system is no longer able to read and write from the disk and freezes. First I tried to set "nvme_core.default_ps_max_latency_us=200" in my kernel parameters, but that didn't work for me. I also tried 0, 6000, and 1000000 as values, but also no luck. The last reply in the thread suggests to add "pcie_aspm=off" in order to explicitly disable ASPM , and that did the trick!

I'm having an issue with booting up and waking up on a new laptop. I'd like to know if there are possible solutions or if I should return the device? I've used Ubuntu for a few years now but only have a basic grasp of the more technical aspects of the system. The laptop came with Windows 10 and I installed Ubuntu 20.04 without testing to see if the problem was on Windows too. The problem I'm experiencing is as follows:On startup, the system often hangs on the manufacturer logo. A restart allows me to proceed.The system always loads into GNU grub menu. Selecting "ubuntu 20.04" allows me to proceed.(These last two are more of an inconvinience but I suspect might point to a deeper issue) My primary issue is this: the system often crashes after waking in an odd way. First, the system hangs on the login screen for a few minutes (Not what I would expect from a new SSD).Next, once I've logged in, apps don't function as expected. For example, in Firefox, I can open new tabs but can't access websites.After interacting with each app (in a limited way) for a period it will crash.In this "mode" the system doesn't power-off from the user interface so I'm forced to do a hard reset. After the crash and on startup, the system loads grub command line. Input "exit" allows me to proceed. This crash after waking problem doesn't occur if I wake after a brief sleep (a few seconds). Sometimes error messages display after the crash but not always. A few examples are: Read-error on swap-device (253:1:1015920) (the number varies)Buffer I/O error on dev dm-0, logical block 0, lost sync page writeEXT4-fs error (dm-0): I/O error while writing superblockpsmouse serio1: elantech: failed to query capabilities. I've updated software, flashed BIOS and hardrive firmware. I used to recieve walls of system errors related to systemd-journald but, since the BIOS updates, I receive fewer error messages however the core issue is unresolved. I've seen similar issues attributed to a GPU drivers however I'm using on board graphics. My current suspicion is that there is an error with the hardrive.

Appreciate any help!
