Nope, was wrong. It is broken in upstream too. My system:

As far as I can tell it is fixed in upstream. And this bug already
marked as "Confirmed" if I am understand this correctly.

2016-10-07 Thread Vadim Shalts
Unfortunately I don't monitor precisely kernel version and updates. Hard
to say in what state was system prior to current one.

And I don't have strong scenario to reproduce this issue. But it hit me
be several times. I know cases in with it looks like appear. Switched to
upstream kernel. So far so good. Will continue to monitoring. If I will
not be able to reproduce this issue during next week then I will mark
bug with 'kernel-fixed-upstream'.

[Kernel-packages] [Bug 1626517] Re: Access to some folders hangs and in dmesg see kernel BUG report

2016-10-03 Thread Joseph Salisbury
Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.8 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.
