Then to remove it I ran: sudo tune2fs -O ^fast_commit /dev/nvme0n1p2 which still resulted in errors until I rebooted and appended "fsck.mode=force" to the Linux boot cmdline; the system now runs OK. Hope this helps debug the fscrypt/fast_commit interaction. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
