After i managed to reboot (REISUB). I've look at dmesg log, and at the end of the log theres an error for the last boot
24.340774] kernel: amdgpu 0000:04:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0000 address=0x4a68002a0 flags=0x0070]. So i added iommu=soft to the grub.cfg and reboot booted into 5.4.0.29-generic kernel 5 times so far and it seem to be boot fine now ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1876835/+attachment/5367316/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876835 Title: black screen before login on 5.4 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1876835/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
