Public bug reported:
On an NVMe system I'm using, Ubuntu 16.04.1 regularly seems to trigger
off a kernel panic against somepart of the NVMe driver it looks like,
after which the logs get filled with entries over and over again of:
"bad: scheduling from the idle thread!"
Here's the initial stack trace that seems to trigger off the bug:

Title:
NVMe triggering kernel panic followed by "bad: scheduling from the
idle thread!"
Status in linux package in Ubuntu:
New
Bug description:
On an NVMe system I'm using, Ubuntu 16.04.1 regularly seems to trigger
off a kernel panic against somepart of the NVMe driver it looks like,
after which the logs get filled with entries over and over again of:
"bad: scheduling from the idle thread!"
Here's the initial stack trace that seems to trigger off the bug:
