Title:
[trusty] 3.13.0-167-generic repeatedly trips kernel paging request
BUG:
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Trusty:
Confirmed
Bug description:
While trying to diagnose a problem with getting a kernel BUG: Bad page
map in process retriever (retriever is the name of our serving
binary), causing the serving binary to crash, we tried upgrading from
3.13.0-121-generic to 3.13.0-167-generic and instead started more
regularly tripping a different bug that hardlocks the system when we
attempt to stop & restart the affected process.
We are running Trusty on AWS in i3.xlarge instances.
