I intend to do this, but I expect it to eat up a few hours of time so
just haven't gotten around to it.

[Kernel-packages] [Bug 1767452] Re: kernel oops when I undocked

2018-05-02 Thread Frew Schmidt
Good news! the 4.17.0-rc3 kernel *fixed this issue*!   You can get it
here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17-rc3/  I only
tried undocking once so far but hey, I was able to undock and redock and
there was no oops in dmesg.  I will likely try again later throughout
the day for various meetings.  Will update here if I have any problems.

2018-05-01 Thread Frew Schmidt
I just realized why I thought this was not predictable.  The system
continues to function just fine after the Oops *until* I close my
laptop. Once I close my laptop the whole thing freezes and does not
recover.  Attaching one last kernel log and then will leave it alone
till someone asks for more detail.

I reproduced this this afternoon with the latest stable kernel (4.16.6.)
See attached subset of the kernel log.  I'll try with 4.17 tomorrow.

2018-04-30 Thread Frew Schmidt
I do have a Thunderbolt dock, but it is not so trivially reproducable
for me.  Most of the time I can undock and redock just fine.  I
suspect I did something in an unusual order, like closed my laptop and
*then* undocked, instead of undocking first.
