Dear Kai-Heng, I'm not quite sure what you actually want me to try ... but Kernel 5.12-rc8 with "nomodeset" & without "amdgpu.ip_block_mask=0xfffffdff" gives:
- amdgpu kernel module not loaded, Xorg amdgpu driver not loaded - Xorg vesa driver loaded & no acceleration => high CPU load - suspend seems ok but fails on resume (display does not wake up) - hibernation/resume ok So, the result is similar to what I reported in scenario 1) of my comment #5 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920674 Title: AMD A8-7680 (amdgpu): broken Xorg acceleration and hibernation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1920674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
