Hi Antonio,

quoted

it seems so. It happens at least once at boot time.
I will try wireless-testing and see what happens. Then I will apply your patch.

The problem is there either with wireless-testing and with
wireless-testing+your_patch.

If it can somehow help, I also got several stack trace regarding intel_iova
functions. But then the I got kernel panic and I was not able to copy the
messages.

[MV] Depending on how you set it up, perhaps the stack trace was saved in one of the syslog files in /var/log/...

Thanks!

Can you please re-run with debug=1 and send the whole log ?
This will give a better indication on when the issue occurs.

Does this help?

I applied patch in comment 17 on linux-3.3.4. IT didn't help but this time I got
the WARNING even with debug=1. Log is attached.

Is there any particular kernel debugging option I could enable to make the log
more verbose?


Cheers,
