Title:
  Sysrq trigger g cause system hang on Ubuntu 15.10

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I are using kgdb to debug kernel driver. The break point and sysrq
  work fine on Ubuntu 14.04. But when I upgrade Ubuntu from 14.04 to
  15.10, the sysrq trigger g (alt+sysrq+g) doesn't make gdb break and
  system hangs. It is a regression. The issue only happens after kernel
  booting up. It is OK during kernel booting.
