I have tried as described here (nvme_core.default_ps_max_latency_us=5500 ... etc.).

Problems:

  • Shift key no longer gives access to the boot menu, so I can't complete it.

  • Keyboard and mouse freeze 10-15 seconds after boot.

  • During boot I got "critical medium errors". (How to see them again?)

I have chosen the erase disk install Ubuntu option.

I installed Ubuntu 23.04. by:

A) disable secure boot in the uefi.

B) "In the GRUB boot menu, press e to edit startup parameter. Add nvme_core.default_ps_max_latency_us=5500 after the end of "quiet splash" Ctrl-x to boot up, the installer should detect this disk in partition step."

Step 2 and 3 here:
