[Bug 1172325] New: Full disk encrypted machine boots roughly 1 of 5 attempts
http://bugzilla.opensuse.org/show_bug.cgi?id=1172325 Bug ID: 1172325 Summary: Full disk encrypted machine boots roughly 1 of 5 attempts Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Bootloader Assignee: screening-team-bugs@suse.de Reporter: itaranto7@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- This are probably 2 different issues, but since I'm not really sure I will post them anyway... I'm using a setup like the one explained here: https://en.opensuse.org/SDB:Encrypted_root_file_system I have only one disk, /boot/efi is in a separate partition and the rest is in a LVM physical volume. The physical volume is composed of 2 logical volumes: Btrfs for / and a swap volume. The first issue appears in the GRUB passphrase prompt, I would say that half of the time, it apparently hangs after entering the passphrase. The message I see is: ... Slot 0 opened Please press 't' top show the boot menu on this console The second issue appears after successfully decrypting the master key, once in the GRUB graphical menu, sometimes it hangs and does not displays plymouth. In both cases, Ctrl+Alt+Del works correctly to reboot the machine. The only workaround I know is to attempt booting several times but it's really annoying... -- You are receiving this mail because: You are on the CC list for the bug.

I'm using a laptop which has a 60Hz built-in display and an external monitor with 144Hz. I noticed that in GRUB, when my second monitor was on, the screen blinked in a regular interval (like 10 seconds). So, I turned of the monitor and I attempted several logins without hanging. I will check if it needs to be reported upstream. -- You are receiving this mail because: You are on the CC list for the bug.
