[Kernel-packages] [Bug 1589910] Re: [regression trusty] oops/sig 4: power7_enter_nap_mode+0x0/0x18

2016-06-14 Thread Kamal Mostafa 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  SRU Justification:

  = Impact =
  Since kernel 3.13.0-46 there was a incorrect backport of a stable patch which 
causes several oops messages and ends with an automatic reboot. Which renders 
all kernels since then to be unbootable on ppc64el. This happens because 
instead of the function address to power7_enter_nap_mode, the change 
accidentally loads the address of a related symbol table.

  = Fix =
  Pick up the alternate declaration of the function label as it is in the 
original upstream change (commmit 8117ac6 powerpc/powernv: Switch off MMU 
before entering nap/sleep/rvwinkle mode). In 3.13 this requires one more change 
because there is one call site that refers to a label name which would be 
implicitly generated by the macro that gets replaced. This was done upstream, 
too, in (b1576fe powerpc: No need to use dot symbols when branching to a 
function).

  = Testcase =
  Trying to boot current Trusty kernels on a Power8 host fails all the time. 
With the change applied the host comes up without errors.
