2017-05-11 Thread Seth Forshee 
*** This bug is a duplicate of bug 1674838 ***
https://bugs.launchpad.net/bugs/1674838

Please note that we did confirm this was caused by a couple of the
Power9 enablement patches from bug #1671613:

 6e2a092a48d3 mm: introduce page_vma_mapped_walk()
 3000e033152a mm, ksm: convert write_protect_page() to use 
page_vma_mapped_walk()

These seem to only be providing context for the third patch:

 c228a1037cd6 mm/ksm: handle protnone saved writes when making page
write protect

Based on the commit messages I don't believe they were intended to
provide any functional change. The first claims to only be introducing a
new interface, and the second says that write_protect_page() should use
the new interface "for consistency."

For that reason I've proposed we revert the patches and replace it with
a backport of c228a1037cd6 instead.

https://lists.ubuntu.com/archives/kernel-team/2017-May/083976.html

However 6e2a092a48d3 does contain some changes that seem unrelated to
the new interface, could you please advise whether or not these need to
be reapplied?

[Kernel-packages] [Bug 1680390] Re: Ubuntu17.04: Kernel Oops: Exception in kernel mode, sig: 5 [#1] during Avocado KVM Test runs [Regression]

2017-04-20 Thread Seth Forshee 
Realized that I made a mistake above. Rather than d19469e84158 I meant
this one:

[Kernel-packages] [Bug 1680390] Re: Ubuntu17.04: Kernel Oops: Exception in kernel mode, sig: 5 [#1] during Avocado KVM Test runs [Regression]

2017-04-20 Thread Seth Forshee 
We've been getting a number of other reports of this problem. I've been
trying to reproduce it locally, without any luck so far. However it does
appear that the problem happens only in zesty kernels and not with
upstream 4.10 stable kernels, which suggests that one of the backports
or sauce patches we've applied. The stack trace suggests a problem with
migration (or possibly KSM).

Going through those sorts of commits related to the kernel mm code, a
few stand out based on the size of the changes and the code they're
touching. All of them are backports requested for power9 on bug
#1671613.

6e2a092a48d3 mm: introduce page_vma_mapped_walk()
3000e033152a mm, ksm: convert write_protect_page() to use page_vma_mapped_walk()
c228a1037cd6 mm/ksm: handle protnone saved writes when making page write protect

Some upstream bug fixes reference these patches too (but no mention of
the BUG we're hitting):

d19469e84158 power/mm: update pte_write and pte_wrprotect to handle savedwrite
d75450ff40df mm: fix page_vma_mapped_walk() for ksm pages

I'm going to try to set up the Avocado tests today to see if that allows
me to reproduce. If you are able to reproduce reliably, you could try
applying the fixes above to see if they help, or try bisecting the
patches applied to zesty on top of upstream 4.10 to identify the patch
which causes the issues.

[Kernel-packages] [Bug 1680390] Re: Ubuntu17.04: Kernel Oops: Exception in kernel mode, sig: 5 [#1] during Avocado KVM Test runs [Regression]

2017-04-06 Thread Tim Gardner 
Satheesh Rajendran - please try the kernel intended for release
(Ubuntu-4.10.0-17.19) that is currently staged in -proposed. There have
been multiple stable updates applied since 4.10.0-14. I'd also like to
know if this is reproducible given that I've seen several bugs
complaining of the swapops BUGON, though so far all of those bugs seem
to have been related to the use of Firefox.
