Subject: [3.6.6] panic on reboot / khungtaskd blocked? (WARNING: at arch/x86/kernel/smp.c:123 native_smp_send_reschedule)

Hi,

during playing with new ups i've caught an nice oops on reboot:

http://imgbin.org/index.php?page=image&id=10253

probably the upstream is also affected.

BR,
Paweł.

Hi, Paweł

Are you using a clean 3.6.6 without any modify?

Looks like some threads has set itself to be UNINTERRUPTIBLE with out
any design on switch itself back later(or the time is too long), are you
accidentally using some bad designed module?

BTW, it's better to paste whole log in mail with text style not a picture.

yes, pure 3.6.6 form git tree with modular config.

hmm, hard to say. mostly all modules are loaded automatically by kernel.

Could you please provide the whole dmesg in text? your picture lost the
print info of the hung task.

And please try the latest kernel, the issue may already solved(if it is
a issue...).

hmm, i have one observation.

during rc.shutdown there're messages on console like this: Cannot stat file /proc/$pid/fd/1: Connection timed out
afaics this file descriptor points to vnc log file on a remote machine, e.g.:

# ps aux|grep xfwm4
eda 1748 0.0 0.0 320220 11224 ? S 13:08 0:00 xfwm4

# readlink -m /proc/1748/fd/1
/remote/dragon/ahome/eda/.vnc/odra:11.log

# mount|grep ahome
dragon:/home/users/ on /remote/dragon/ahome type nfs (rw,relatime,vers=3,rsize=262144,wsize=262144,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.2.121,mountvers=3,mountport=45251,mountproto=udp,local_lock=none,addr=10.0.2.121)

so, probably during `killall5 -TERM/-KILL` on shutdown stage something sometimes go wrong
and these processes (xfce4/vncserver) survive the signal and hang on the nfs i/o.

Paweł.

We can report the bug to driver folks, but have to make sure whether
the hung thread is belong to it firstly, so we need the hung task info
(at least the name).

I'm not sure what's the environment we faced, but setup debug method is
necessary, 'script' may help you to record the dmesg even when remote
console hung.

If it's really hard to get dmesg, please try below modify and
see whether the info print out on console.

Michael Wang

This can only tell us what's the task in UNINTERRUPTABLE state, but with
out time info, we can't find out which one is the hung task...

Probably all of the ones in D state waiting on NFS are the issue - but
as I understand it, with modern kernels processes are supposed to be
killable while waiting on NFS I/O. Maybe there's a bug that affects
this, though?

That sounds possible, I thing Paweł can try to stop using NFS(if
possible) and take a look, if the issue disappear, then it's time to
report the bug to NFS folks.

It's really NFS related. E.g. in trace

its response that the data was written.

Well, in that particular trace we are not waiting for PageLock but on
PageWriteback bit as I wrote. But otherwise yes, NFS set PageWriteback bit
and sent the data from the page to the server. When the server responds,
the PageWriteback bit will get cleared and could continue. But the response
didn't come.
