Today is June 6, 2022.Not too late to link to this post.
I am on Ubuntu 22.04 on Raspberry Pi 4 with 8GB RAM. My Chromium-browser was working fine (then I did some change to /boot/firmware/config.txt to enable audio. (Later I found it just needed a simple change in the pulseaudio setup). But I did not revert the change I made to config.txt. That remained there. Now when I rebooted the system, I got the DRM_IOCTL_MODE_CREATE_DUMB failed error: Cannot allocate memory. Prominently displayed on terminal, since I started chromium-browser with terminal command.
When I read the posts here, I felt a connection. That it has something to do with configuration. Then I reverted the change I made earlier.
hdmi_drive=2
So I commented the line out. Now my ChromiumBrowser works like a charm.
So for all Raspberry Pi experts who face a crash please check this line. Since this occurs even now in 2022, it can be easily simulated. I still don't know the relationship between enabling hdmi_mode=2 and the memory allocation. That some expert could tell us.
Note: I was on a 4K HDMI TV connected to Raspberry Pi 4 8GB RAM system.

A typo in my earlier message:
hdmi_drive=2 and not hdmi_mode=2

REgret the above post. It was invalid. The same error came back.
Now I created cma=384M in /boot/firmware/cmdline.txt and now it seems to work.
Thanks for the post made earlier .
