Hi Clement Yuan, thanks for the attachments, however it looks like this is the output for 4.15.0-47, can you try to boot with an older kernel that without this issue and provide these information again?
In the mean time, I am trying to install Ubuntu 18.04 on XFS file system for the Dell G7 here to see if that is a cause (although the HW is a bit different from yours, graphic card is GTX1060, wireless card is Atheros QCA6174.) But I can't boot the system with root file system install on a XFS partition, what is your configuration? And how did you install your / to the XFS filesystem? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821027 Title: Boot time increase since 4.15.0-46 on Dell G7 7588 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1821027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
