[arch-general] Shutdown and reboot not working after last weekend update

[Victor Silva]

Folks sorry for cross posting this at forum and mailing lists but so far no
solution came there.

Folks after the last upgrade I can no longer shutdown nor reboot my machine
(I'm using it as root). The command simply hangs and nothing happens. I've
done some research and found
https://bbs.archlinux.org/viewtopic.php?id=141155 this but that does not
seems to be my issue. I'm clueless which logs can I provide you in order to
diagnose what can be the problem? Important thing, I have only 1 session
running and the system report going down still it never  gets past the tty
broadcast as it seems.

Ideas?

This came after a update last weekend, the content of the update is here:

Dmesg output is here

My last boot log is here:

My fstab (which was asked on the forums is here):

Is it somehow related?

I've googled a bit and came with a solution which gives us some insights

Seems something is not properly unmounting.

SO you can for it with:

echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger

Forcing a shut down, still no clear way out of it. Ideas?

I was asked to perform a fsck which failed.It reported /dev/sda5 was
mounted. Is there any proper way I should use to call fsck? I did create a
/fsck file on / is there other more appropriate command to do it? Problably
you asked for my fstab expecting an error like this right? Would it be
better to run fsck from a livecd?
