Bug ID: 213917 Summary: Screen starts flickering when laptop(amdgpu) wakes up after suspend. Product: Drivers Version: 2.5 Kernel Version: 5.13.6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: utkarsh.naveen@gmail.com Regression: No
I have an ASUS FX505DT with an AMD Ryzen 3550H APU. This is not a new bug and it was fixed in kernel v5.6 with commit hash: eb916a5a93a64c182b0a8f43886aa6bb4c3e52b0
I haven't had the time to test out each of the kernel versions individually, but this bug isn't there in Linux v5.12.6 and only appeared after I updated to v5.13.5.
## Steps to reproduce 1. Let the laptop suspend. 2. Wake it up with some keypresses or something. 3. After waking up, the screen starts flickering on/off every second.

--- Comment #1 from Samuel Sieb (samuel-kbugs@sieb.net) --- I've just run into this as well. I upgraded the laptop to 5.13.12 and the display doesn't resume properly as described. The cpu is "AMD A10-9600P RADEON R5". The only relevant messages in the journal are 4 lines like: amdgpu 0000:00:01.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0000 address=0x10aa25720 flags=0x0070] with a different value for address in each one.

--- Comment #2 from Samuel Sieb (samuel-kbugs@sieb.net) --- I just tried with 5.14.1 and resuming works again. I still get those messages in the log, so apparently they aren't relevant to this issue.
