When valid /etc/fstab mount options are used for an f2fs partion the kernel generates a warning message /etc/fstab entry f2fs rw,relatime,discard,user_xattr,acl,background_gc=on,active_logs=6 0 0 Sample error messages F2FS-fs (sda2): Unrecognized mount option "user_xattr" or missing value F2FS-fs (sda2): Unrecognized mount option "acl" or missing value. Using standard x86_64 Arch Linux kernel with the following f2fs config options CONFIG_F2FS_FS=m CONFIG_F2FS_STAT_FS=y CONFIG_F2FS_FS_XATTR=y CONFIG_F2FS_FS_POSIX_ACL=y CONFIG_F2FS_FS_SECURITY=y Even if (with the above options) user_xattr and acl are default on the kernel should not warn about them being used as mount options or at least not warn as unknown options.
I also am having this bug when installing arch on root partion as it hangs after mounting due to this issue , followed Arch guide with ext4 and there are no issues.
I corrected my problem so it's fine for me
