Razer 15 advanced crashes when trying to suspend

I recently purchased Razer Blade 15 Advanced Model - (OLED 4K Touch 60Hz - GeForce RTX 3080) and installed Ubuntu 21.04, dual boot with Windows.

Since the minute I installed I'm having some random flickering and system freezes, meaning everything freezes quite randomly (sometimes after a few hours, sometimes less).

I tried a ton of solutions offered online to solve the freezing problem, now it doesn't seem to freeze, but instead whenever I close and open the lid or just suspend it, it either reboots or crashes with a "*ERROR* CPU pipe A FIFO underrun" error or is stuck in a terminal login.

My current setting is the following:

• CUDA 460.91.03 (I tried 470 and 495 but then I had my laptop randomly freezes)
• I disabled secure boot
• In grub I added GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
• Bios version is 1.10
• PRIME profiles in Nvidia x server settings is set to NVIDIA On-Demand

If there's any further information needed, just let me know what to run/check and I will.


Any help in solving it will be greatly appreciated.

 

Could you please try this on your grub?

Update grub and restart:

Code:

update-grub && systemctl reboot
