Well,

sysrq at least works, the output of

$>sudo strings /var/log/messages | grep -e 'Jan 21 17:17:46' -e 'Jan 21 17:18:..' -e 'Jan 21 17:2[01]:..' > messages.txt

is attached - the .config is attached too.

I'm seeing a very similar hang with an ubuntu guest and a custom kernel.
I'm on commit 0dc3fd0249a, and it's 100% reproducible every time I run KVM.

Cc-ing a few more folks...

Did a little more LKML digging and found this:

http://marc.info/?l=linux-kernel&m=139038631607917&q=raw

Peter's fix works for me. I'm also running a CONFIG_PREEMPT_VOLUNTARY=y
config.

Hhm, that patch cannot be applied to 3.13.0 kernel :-(

I do have :

n22 /usr/src/linux # zgrep CONFIG_PREEMPT /proc/config.gz
# CONFIG_PREEMPT_RCU is not set
CONFIG_PREEMPT_NOTIFIERS=y
# CONFIG_PREEMPT_NONE is not set

What makes the situation really annyoing - sometimes I just can restart my wlan device it the system works normal, but sometimes the whole system hangs and for those cases then sometimes not even sysrq buttons do work.

What I see in /var/log/messages are those lines :

Can you reproduce it with the wlan driver disabled completely?

With 3.12.2 at the same 32 bit Gentoo Linux I experienced a similar thingin a complete different scenario: I umounted a loop-mounted file, on which I created and filled a btrfs file system before (/usr/portage FWIW - I'm a Gentoo user) and the systems becomes very slowly and /var/log/messages shows :

Hhhm, that fix seems not to be applicable for 3.13.x
With 3.13.2 I removed multimedia, sound and wlan and few file systems from the kernel's config, now at least the kernel doesn't hang, but I do still get while trying to start a virtual machine (and please note, I run into a similar issue while just umounting a btrfs file system) :
