Raspberry Pi 3 ARMv7 - nostalgic arch

[captain]

Hi all,
I recently installed archlinuxarm on the latest Raspberry Pi and all was well until I did the usual pacman -ySu.
It seems that for some reason, the newly installed arch version isn't properly integrated. SSHing into the machine works without any issues, but I get this error:
$this->bbcode_second_pass_code('', '[root@rapiserv ~]# iptables -L
modprobe: FATAL: Module ip_tables not found in directory /lib/modules/4.4.19-1-ARCH
iptables v1.6.0: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.')
It's actually not a great surprise, since that folder does not exist, but a newer version:
$this->bbcode_second_pass_code('', '[root@rapiserv ~]# ls /lib/modules/
4.4.21-1-ARCH extramodules-4.4.21--raspberrypi')
Uname also shows the wrong version:
$this->bbcode_second_pass_code('', '
[root@rapiserv ~]# uname -a
Linux rapiserv 4.4.19-1-ARCH #1 SMP Tue Aug 23 19:18:03 MDT 2016 armv7l GNU/Linux')

The suggestions found on the internet mostly suggested a reboot, which didn't help.
I also did $this->bbcode_second_pass_code('', 'pacman -Qnq | pacman -S -'), rebooted and still same error.

I'd be greatful for any further suggestions

EDIT:
downgrading like so:
$this->bbcode_second_pass_code('', 'pacman -U /var/cache/pacman/pkg/linux-raspberrypi-4.4.19-1-armv7h.pkg.tar.xz')
worked as a temporary solution to the issue.
I'd still prefer to stay on the regular update cycle... if anyone has suggestion, that'd be grand!

Make sure /boot is mounted when you update.

Also, it is not ARM7, its is ARMv7 (small letter, huge difference)

Your used boot partition is not properly mounted at the time of kernel package install.

Thus, the kernel being booted is 4.4.19, and the installed modules are 4.4.21

[captain]

ok, thanks.
so, please tell me, how do I mount boot properly?

[WarheadsSE]

Where is your boot partition? Does it show in `mount` ?

Default instructions, should be /dev/mmcblk0p1 on /boot

[captain]

thanks again!
It worked this time. After checking with 'mount', there was no specific entry for boot, although it was read/writable by root.
mounting boot manually, updating and rebooting resulted in a system in working order as far as I can tell.
Should I add the boot partition to fstab? On an older raspberry I noticed there is one for boot..

Strange, my Arch install some month ago created an entry in fstab.

$this->bbcode_second_pass_code('', '/dev/mmcblk0p1 /boot vfat defaults 0 0')
