I also tried ubuntu 22.04 on usb stick and it freezes.
So, should I install 22.04 with the workaround ?
I think it is a problem with intel cpu. Complete ref is :

Perhaps you need both intel_idle.max_cstate=1 and i915.enable_dc=0 parameters?
According to the above link, some chips might need both.
Also, are you able to try a more recent Ubuntu version?

If your system did not reboot, then CPU or other HWs hung up. This is

Do we have any new information about this bug? Do we know what's causing it?
More importantly, do we have any idea whether it's going to be fixed in an
upcoming kernel? Or is our only option to downgrade?
It's pretty sad that we can't use our laptop as an actual laptop.
With my Dell Latitude 7490 running kernel 5.13.0-22 on Ubuntu 21.10, it
freezes around the login screen.
However, if I boot with my dock (Dell WD15) connected, it seems to work fine.
Until I disconnect the dock... then it freezes a few seconds after.

Hello Kleber,
I tried kernels 5.11.0-40 and 5.13.0-21. My machine freezes with both.

after few minutes. Kernel 5.4.0-90 works.
My version is Ubuntu 20.04.3 LTS. Machine is a Dell Latitude 7390 with

If updating to the latest 5.11 kernel still doesn't fix the problem,
please try installing 'linux-generic-hwe-20.04-edge'. This HWE -edge

would be a good data point to know whether it fixes the issue.
