Hi!
I had this with something in between 3.7-rc3 und 3.7-rc4 after inserting
and removing an USB stick. This example is with a kernel + f2fs patches v3,
but I had this with 3.7-rc3 as well.
I think it happens on removing the USB stick, but I am not exactly sure. It
might have happened a bit earlier.
Host is an ThinkPad T520.
Is this known already? I didn´t find anything in LKML or git log from today.
Thanks,
Martin

Ok, so it's not a new thing introduced in 3.7-rc4 (which is good, as
there wasn't any USB patches added between -rc3 and -rc4.)
Does it also happen on -rc2? Anything older? Can you run 'git bisect'
to try to track it down?
thanks,

It appears to be worse with 3.7-rc1. The machine basically locked up a few
moments after inserting the stick.
First time I was on some tty and I saw lots of backtraces flowing by the
process of which the BTRFS on /, which resides on an unrelated internal
Intel SSD 320, was switched to read only. There have been pauses between
backtraces. Second I was in KDE session which basically locked up soon as
well. No mouse pointer movements where possible, no switching to tty1.
I only have the last part of the backtrace of the first occurence as photo.
Nothing was saved on SSD.
I do not want to go an earlier 3.7 version than rc1 on this production
machine.
I can try rc2 tomorrow.
How to proceed? With 3.7-rc3+somegit I was at least able to save out some
dmesg output to the SSD before I rebooted the machine. I can try to get
some longer backtrace this way.
Oh, I see I have a dmesg > file that actually made it to SSD. This one is a
tiny bit longer than the first one. Attached. The screenshot of shortly
before I rebooted the machine is in [1]. That was some seconds after the
BTRFS read only part slipped by. These are from the same, first occurence.
I wonder that this apparently hasn´t been reported already. It may be
configuration specific. I attached config file. It was same for plain rc3 and
just with some f2fs options added for the f2fs kernel in my first post.

git bisect bad 73d4066055e0e2830533041f4b91df8e6e5976ff
The first one I skipped was having these issues on boot already. The
second one I skipped was just a few commits after the first one, I didn´t
test the second skip.
I removed USB mouse in order to avoid having any removable USB devices
attached during testing.
The first bad commit is:
commit 73d4066055e0e2830533041f4b91df8e6e5976ff
Author: Chuansheng Liu <chuansheng.liu@intel.com>
Date: Tue Sep 11 16:00:30 2012 +0800
USB/host: Cleanup unneccessary irq disable code
Because the IRQF_DISABLED as the flag is now a NOOP and has been
deprecated and in hardirq context the interrupt is disabled.
so in usb/host code:
Removing the usage of flag IRQF_DISABLED;
Removing the calling local_irq save/restore actions in irq
handler usb_hcd_irq();

But:
This ony happens with threadirqs option!
When I remove threadirqs from kernel command line and reboot with this
last bisect kernel USB sticks work.
That may explain why nobody else has seen this.
So I will try a 3.7-rc4 now, but without threadirqs enabled.

Just another note:
irq/16-ehci_hcd was taking >99% CPU. It had PR -51 in top and I think this
was the task that made the CPU core stuck.
I have a short dmesg piece from the bad commit kernel. Attached.

Thanks your pointing out, the USB HCD irq handler is designed to execute in irq handler with irq disabled.
When threadirqs is in commandline, it will be executed in thread context with local irq enabling, which causes
this hardlockup.
I prepared one patch, could you have time to test it? Thanks. Sorry for missing threadirqs case.

Subject: [PATCH] USB/host: Mark USB HCD irq as non-threaded
Mark USB HCD irq as non-threaded. This prevent one crash/hard lockup
when "threadirqs" is on the kernel commandline.
And this interrupt handle is handling critial events which should not
be in thread context.

(KMail outputs your mail as base64 and cut&paste did not retain tabs.)
gives:
1) with threadirqs enabled: No action at all when inserting USB sticks,
nothing in dmesg.
2) with threadirqs disabled: USB sticks work normal.
So your patch fixed the CPU lockup by disabling USB altogether, when
thread IRQs are active it seems. :) Or I made a mistake while manually
applying your patch. Seems okay to me tough.
PS: I think that thread IRQs for USB based interrupts might not be a good
from another experience I had with an ThinkPad T42 and USB sound card
Sonica Theater. I was not able to have it produce fluent sound with
Phonon Gstreamer or Phonon VLC from Amarok playing back music unless
I disabled threadirqs on that machine as well. Often I just heard a view
seconds of sound at the beginning and then nothing more at all. Works fine
with thread IRQs disabled. At least from VLC backend. Gives about 30% CPU
usage for that interrupt with thread IRQs enabled. Card is USB 1.1 only.
Ciao,

No. The problem is caused by the commit above. USB with threaded
interrupt handlers worked perfectly fine in the past.

NAK. This is exactly the wrong thing to do.
We want to be able to run that code in an handler thread. So you
removed the local_irq_save/restore() in the driver code and with
forced threaded irqs this breaks. Now setting IRQF_NO_THREAD is just
working around the problem that the above commit broke it.
There is no hard requirement to run USB interrupts in hard interrupt
context. I'd rather see the above commit reverted and then a proper
analysis done why removing local_irq_save/restore() breaks forced
threaded interrupt handlers.
Thanks,

The reason is that removing local_irq_save/restore() in function usb_hcd_irq().
The hard lockup analysis is:
CPU3
Usb_hcd_irq() -->
ehci_irq -->
spin_lock (&ehci->lock);
...
if (status == ~(u32) 0) {
At this time, one hrtimer is coming:
ehci_hrtimer_func() -->
spin_lock_irqsave(&ehci->lock, flags);
Due to the spin_lock has been hold before, it causes the deadlock.
The dmesg is as below:

As Martin's experience:
"I think that thread IRQs for USB based interrupts might not be a good
from another experience."
Maybe it shows something.

As you said, we can revert the patch directly, or submit a new patch to just add
local_irq_save/restore() back.
Anyway, hardlock reason is there.

Let me revert this for now, as it's obviously causing problems.
