Hello,
I don't really know where the issue comes from (ie laptop, kernel, hardware...) so I decided to post this in the Newbie corner.
First I wanted to mention it is a new issue on my laptop, I'm not quite sure when it really started, maybe after a pacman -Syu but not certain. Everything else works as usual.
So, every time I shutdown, i get the normal "::Stopping Cron Daemon [DONE]" etc lines, and the last line is "SHUTTING DOWN", but then the screen freezes. After a few minutes, some lines appear on the screen (i'm retyping these lines manually by copying from a photo, because i can't save these lines anywhere since all disks are alreday unmounted)
[ 785.707892] irq 16 : nobody cared (try booting with the "irqpoll" option)
[ 785.708141] handlers:
[ 785.708198] [<ffffffffa00064f0>] usb_hcd_irq
[ 785.708254] [<ffffffffa0168220>] mel_interrupt_quick_handler threaded
[ 785.708381] [<ffffffffa0223a40>] sdhci_irq
[ 785.708428} Disabling IRQ #16
Then nothing, and I need to shutdown my computer manually.
I tried booting with the irqpoll option but it changed nothing. Googling didn't bring me much help neither.
I thought this might help:

that message seems to be related to multiple devices using the same IRQ, but they are not cooperating well.
(Note : it also happens with irq 17).
The cause is often an addon card that conflicts with onboard stuff.
Please post the output of
$lspci -v
.

that means 2 intel devices and 1 3rd party use irq 16.
The O2 Micro 8320 is a smartcard reader, try blacklisting the sdhci-pci module to see if that allows a normal shutdown.

Hey that did the trick! Thanks a lot. I'll just turn the mod on again when I need to read smartcards.
