I've attached the dmesg output from the boot after and the systemd journal from a reboot and the boot after: perhaps you will be able to find = this info there. Otherwise please advise me if I need to add some kernel boot params or configure some other log gathering or apply some patches to my kernel to collect some more useful data: to be honest I don't know how to proceed fur= ther from here on my own. Thanks :) --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
