There are no entries in the journal for those particular boots I'm afraid. That is, the journal is empty if I boot without "nomodeset" or without "amdgpu.ip_block_mask=0xfffffdff". There are some very quick boot messages appearing on the screen before it turns all black, but nothing in the log.
I rebooted several times to make sure it is not a random behaviour. I even tried "verbose debug" kernel boot parameters with no success. I packed all the logs from that particular date in case I analysed the situation wrong. What can I do now? ** Attachment added: "journal_AMD_A8-7680.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1920674/+attachment/5493224/+files/journal_AMD_A8-7680.txt -- 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
