I met the bug, only 'amdgpu.dcdebugmask=0x10' can solved it.

I have tested the lastest kernel.

Title:
  [amdgpu][psr] Screen flickering/ tearing on 6.1/6.2/6.3 kernel

Status in linux package in Ubuntu:
  In Progress
Status in linux-oem-6.1 package in Ubuntu:
  Invalid
Status in linux-oem-6.1 source package in Jammy:
  Confirmed

Bug description:
  After upgrading from kernel 5.19.0-35-generic to 6.1.0-1007-oem there
  is occasional screen flicker/ tear. It happens around every minute; it
  seems connected to window/ pointer movement, but I have no clear way
  of reproducing. Disruption is minor,  but annoying.

  I'm running 22.04 LTS on a new Thinkpad T14s with AMD Ryzen 6850u. The
  system is fully functional. No crashes, nothing breaks.

  Background on the use of 6.1.0-1007-oem: 5.19.0-35-generic breaks
  suspend/ resume on my laptop, see
  https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.19/+bug/2007718.

  In a way, running 6.1 is a 'flight forward', since 5.15.0-67-generic
  (previous 22.04.1 LTS kernel) works well, with working suspend/
  resume, and without screen flicker. But that's an 'old' kernel now,
  missing some nice improvements for the newer Ryzen APUs.
