Title:
  chaoskey interferes with suspend on thinkpad

Status in linux package in Ubuntu:
  Expired

Bug description:
  Thinkpad T450s, docking station, Altus Metrum Chaoskey plugged into
  the docking station - suspend fails often (more than half the time,
  maybe not 100% but easily duplicated in my setup) in that it doesn't
  seem to go all the way down - and on wakeup, lsusb output doesn't
  update, `lsusb -t` hangs when run.  It *may* require "suspend, undock,
  unsuspend" but I'm not convinced...

  Interesting logs include a "blocked for more than 120 seconds"
  traceback after restore that goes through chaoskey_disconnect even
  though the laptop is undocked so it's no longer attached:

[Kernel-packages] [Bug 1762816] Re: chaoskey interferes with suspend on thinkpad

2018-04-11 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
v4.16 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.

request (not going to audit 11,000 lines of apport output if I can at
all avoid it, though.)

[Kernel-packages] [Bug 1762816] Re: chaoskey interferes with suspend on thinkpad

2018-04-10 Thread Mark Eichin 
On inspection of apport-collect output, it doesn't appear to filter out
serial numbers or SSIDs, so I can't submit it.  Also, it seems to have
left out any of the logs where the tracebacks mentioned above were
included; I'll add at least a useful chunk of kern.log surrounding the
problem as an attachment.
