Hi Bogdan! Sorry to hear, that it doesn´t work for you. I fear that you did add the parameter in the same way then I did. So there might be some other difference.
This is my kernel cmdline (cat /proc/cmdline): BOOT_IMAGE=/vmlinuz-4.18.0-0.bpo.3-amd64 root=UUID=bda00e2f-ad36-46eb-a81a-cceb7736ab65 ro rootflags=subvol=VOL_ROOT rootdelay=5 apparmor=1 security=apparmor mce=ignore_ce The apparmor stuff shouldn´t make a difference, it is to my understanding not started at this early stage. I´m not sure about mce=ignore_ce. You might give this a try. I can´t remember the specific issue why I added it, but it was quite likely also related to HP gen8 MircoServer. Hope this helps you for your further investigations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752961 Title: With kernel 4.13 btrfs scans for devices before all devices have been discovered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
