Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

Hi!
It just happened again: my system hangs on Disabling IRQ #16, just ater "Storage is finalized" systemd output. It won't poweroff...
As title says, i'm using latest linux-ck, with bfq scheduler, atom optimized, from gravsky's repo.
Any idea?

Thanks!

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

Exactly the same problem here with linux-ck-k10 3.9.3.. I had to downgrade to linux-ck 3.8.13 for the time being since it doesn't cause any problems.
Any idea is welcome.

Do either of you have HP laptops?  https://bugs.archlinux.org/task/35237
If not, please post this behavior to CK's blog, he or others may have some insights.

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

CK and others suspect this is an issue in upstream.  There are reports including the flyspray I referenced, that show the behavior without the ck1 patchest applied.  If you read through the blog, you will find evidence that the BFS is a very sensitive tool for uncovering kernel bugs due to its design.  Does the same problem occur under 3.9.4-1-ck?

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

It seems solved in linux-ck  3.9.4.
I'll mark thread as solved!

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

...just so people know, if indeed 3.9.4 fixed this issue, it has nothing to do with ck.  The ck1 patchset for 3.9.x has been unchanged since its release.  In other words, this is not an issue caused by it but by upstream bugs.

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

Uhm, it is not yet solved. It is happening again, 3.9.4-2 ck-atom. Probably less often then before (once every 5-6 cycles), but it is happening.
I can only tell you that i tried 3.9.3-ARCH, and it had no problem (it never happened with stock arch kernel), so you said it was an upstream bug (and I forgot about those 2-3days i ran arch kernel, sorry), but i'm not so sure now.
Any idea?

EDIT: next time it happens i'll take a photo, and i'll post here!

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

Happen to me, every reboot/shutdown. Downgrading to 3.8.8 solve the problem. Tried rebuilding using CONFIG_HP_WMI=n didn't solve it. Happens on both stock and ck kernel. I'm on HP Compaq laptop. Will post the journalctl log tonight.

I've solved mine now.. Blacklisted hp_wmi and now I can reboot and shutdown again.. Hope there will be a fix from upstream soon. :-)

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

I have a PF kernel, not CK (and no hp-related hardware), and it happens to me occasionally, but I rarely reboot/shutdown.

However, I frequently put the laptop to sleep and it just hangs  before shutting down the screen. The sleep LED keeps blinking indefinitely (it should only be blinking during sleep initialisation), and no errors are being printed out, but I suspect it is the same cause as with reboot when the aforementioned printout is visible.

It affects ~50% of sleep cycles, which means that when I put laptop to sleep, I lose my work 50% of the time.

@Lockheed: Adjust your tick rate from 300 Hz to 1000 Hz to avoid this problem if 1k is not the default in pf.

Re: Linux-ck 3.9.3 disabling IRQ #16 shutdown hang

Btw, i switched to -ARCH kernel and problems disappeared.
It never happened since last time i used -ck kernel. (by the way i'm now using xorg-session-launcher and user-session-units, so i cannot revert to -ck)
