This is VIA EPIA board with 533 MHz VIA Samuel 2 CPU. Normally, longhaul
is not enabled automatically but with longhaul.enable=1. It used to work
up to 3.14 but in 3.15-rc, different cpufreq-related codepaths block for
long times and cause warnings.
/usr/bin/cpufreq-set --cpu 0 --governor ondemand
is running since boot and hangs in D state.
Running cpufreq-info seems to just hang too.

Probably we haven't introduced a bug here but highlighted one.
12478c: cpufreq: Make sure frequency transitions are serialized
Above commit tried to serialize calls to ->target() routines and this
for some reason didn't work well for you. Probably because something
else was also trying to change freq and it left the system into unworkable
state.
@Srivatsa: Or maybe some barrier stuff is actually required? Or the wake
up event is missed
I don't have a longhaul board and so can't debug this. Probably need some
help from you in debugging this :(

I am quite sure below wouldn't fix it, but just wanted to check
for the corner case :(

I see traces of mutex_lock_slowpath() etc in your logs.. Can you please
enable lockdep and sleep-inside-atomic-section check and let us know if
it complains? Specifically, enable these config options:
CONFIG_LOCKDEP_SUPPORT=y
CONFIG_DEBUG_RT_MUTEXES=y
CONFIG_DEBUG_PI_LIST=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_MUTEXES=y
CONFIG_DEBUG_LOCK_ALLOC=y
CONFIG_PROVE_LOCKING=y
CONFIG_LOCKDEP=y
CONFIG_DEBUG_ATOMIC_SLEEP=y
Meanwhile, I'll spend some time looking at how the longhaul code
interacts with the frequency serialization infrastructure.
Thank you!

Thank you for the logs, but unfortunately they don't give us much
further insight into this issue.

Thank you!

Am I reading it correctly? It looks like we are starting another transition
from notifier chain, but I couldn't figure out how from code.

You need to revert these three patches in the mentioned order.
236a980 cpufreq: Make cpufreq_notify_transition &
cpufreq_notify_post_transition static
8fec051 cpufreq: Convert existing drivers to use
cpufreq_freq_transition_{begin|end}

Okay, I know WTF is going on here. My mistake, but as I said earlier this
patch only highlighted the issue by serializing things its there since last
6-8 months.
I will send out patches shortly, please test them. Description of what actually
happened will be present there in details.
In short, we are sending double notifications here, once from core and once
from driver :(

Indeed, its a case of double invocation of the _begin() and _end()
notifiers. I developed a patchset to fix this in longhaul, powernow-k6 and k7
drivers, before seeing your patchset that does the same thing. However, looking
closer, I don't completely agree with the approach you used to fix the issue,
so I'll post my patches as well (which have a different design).
