[Bug 1506543] Re: openstack instances on arm64 lock up on polling and other situations fairly repeatably

 

FTR, I'm also having problems with the wily arm64 kernel on multi-CPU
machines. I filed that as bug 1531768 as the logs here look rather
different to mine. But maybe it's related.

Title:
  openstack instances on arm64 lock up on polling and other situations
  fairly repeatably

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  While working on deploying arm64 builders in openstack, we found that
  it was pretty easy to wedge them.  Many hang just running ntpdate
  right off the bat.

  William Grant had more direct tests he did, but upgrading from 3.13 to
  3.19 didn't seem to fix things.
