Arch Linux

PS: I'm using HP EliteBook 6930p (VF143UC#ABA).
The message displayed is:
All filesystems unmounted.
Deactivating swaps.
All swaps deactivated.
Detaching loop devices.
All loop devices detached.
Detaching DM devices.
All DM devices detached.
Storage is finalized.

Then nothing happens. I can switch the ttys, and can type letters after these messages are showed.

Interesting.... I get the following[1] if and only if I am using 300 Hz ticks (the Arch default) and the BFS-patched Arch kernel (1k ticks solves the problem); the stock ARCH kernel does not hang at all.

Experiment #1. Can you build from ABS and switch the tick rate to 1k and see if your laptop still hangs?

Instructions to enable alternative tick rate:
1. Add an nconfig option to the PKGBUILD
2. Processor type and features --->
3. Timer frequency (300 HZ) --->
4. Select 1000 Hz
5. Save, compile, and install

Experiment #1.
1. I slimed the kernel with my old config files, it still hangs
2. I used the config in step 1, and changed timer frequency to 1000Hz, it still hangs

Experiment #2. Try the linux-ck package and see if it hangs for you as well.

I just boostraped a fedora system on a btrfs subvol and installed kernel-3.9.1 in fc19. And the fedora system also hangs when I use the 3.9 kernel.
I first found out this problem when I started to use the linux-ice kernel, but it seems that 3.9-rc didn't have this problem.

Perhaps this isn't an Arch bug. Are you planning an upstream bug report?

I built a linux-ck with previous config and set BFS and BFQ, but still hangs.
I suspect that CONFIG_HP_WMI(originally it was 'm') caused the problem, so I unset CONFIG_STAGING and X86_PLATFORM_DEVICES and rebuilt linux-ck, and it can poweroff now.

Interesting, two questions:

1) What made you suspect CONFIG_HP_WMI?
2) If you build the stock Arch kernel from ABS making the change to only CONFIG_HP_WMI=y and #CONFIG_STAGING and #X86_PLATFORM_DEVICES, does it work?

1)
a. I'm using a HP laptop
b. a kernel bug at net/rfkill/core.c:244 emitted during boot, and hp_wmi is in the debug trace

2) I changed CONFIG_HP_WMI to y, but I got a boot failure with 2 kernel bugs(the other is about drm). So I'll try later.

I just set the CONFIG_HP_WMI=n and the problem is solved.

reported to
https://bugzilla.kernel.org/show_bug.cgi?id=58401

CONFIG_HP_WMI=n solved the problem on HP nc6400.

We can use the following patch, but it hasn't been applied in kernel-3.9.4 yet.
https://bugzilla.kernel.org/show_bug.cgi?id=58401#c6

This behavior occurs sometimes in my system, but is not a hp

I suspect that this is not an Arch bug but one created in 3.9.0 (still present) upstream.

Supporting data: See http://ck-hack.blogspot.com/2013/05/bfs-0430-ck1-for-linux-39x.html?showComment=1368430208911#c4581408753333969311 and the comment after it.

I think there might be a bit of confusion with people experiencing similar symptoms from unrelated issues. :) The problem in this bug happens exactly as Iru Dog described in the initial post and is reproducible on every single shutdown or reboot attempt from an HP notebook. The dmesg identifies hp_wmi in the call trace:

-- snip ---
[ 26.244144] kernel BUG at net/rfkill/core.c:244!
--- snip --
[ 26.247083] Call Trace:
[ 26.247124] [<f878522f>] hp_wmi_bios_setup+0x22f/0x34d [hp_wmi]
--- snip ---

Setting CONFIG_HP_WMI=n will resolve the issue, but of course the real fix is to patch the errors in hp-wmi.c as shown here:
http://permalink.gmane.org/gmane.linux.drivers.platform.x86.devel/4493

All of the above confirmed on a Hewlett-Packard HP Compaq 2510p Notebook PC/30C9 ... now just waiting for upstream to patch. :)

Patched in linux-next.

Fixed in linux-3.9.6.

Are you sure?
Long time I used sysv (and grub-legacy, the kernel ..init=..systemd) and recently installed systemd-sysvcompat (and removed "init=" in grub). As soon as I received the same error - the last entry "storage is finalized." (sometimes even "EXT4-fs (sda3): ext4_da_writepages: jbd2_start: 8192 pages, ino 662018; err -30"). My last kernels: 3.10.7, 3.10.9).
My computer is not HP, I have no entry "hp_wmi" in everything.log

M.W. (kenubi): It should be another problem, my problem is caused by a mistake in hp_wmi.c, so it's not related.
