Hi all,
Changes since 20201104:
The drm-intel-fixes tree lost its build failure.
The drm-msm tree gained conflicts against the drm and drm-misc trees.
The mfd tree gained a build failure so I used the version from
next-20201104.
The pinctrl tree lost its build failure.
The akpm-current tree gained a build failure for which I reverted
a commit.
Non-merge commits (relative to Linus' tree): 3085

----------------------------------------------------------------------------
I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ). If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one. You should use "git fetch" and checkout or reset to the new
master.
You can see which trees have been included by looking in the Next/Trees
file in the source. There are also quilt-import.log and merge.log
files in the Next directory. Between each merge, the tree was built
with a ppc64_defconfig for powerpc, an allmodconfig for x86_64, a
multi_v7_defconfig for arm and a native build of tools/perf. After
the final fixups (if any), I do an x86_64 modules_install followed by
builds for x86_64 allnoconfig, powerpc allnoconfig (32 and 64 bit),
ppc44x_defconfig, allyesconfig and pseries_le_defconfig and i386, sparc
and sparc64 defconfig and htmldocs. And finally, a simple boot test
of the powerpc pseries_le_defconfig kernel in qemu (with and without
kvm enabled).
Below is a summary of the state of the merge.
I am currently merging 327 trees (counting Linus' and 85 trees of bug
fix patches pending for the current merge release).
Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .
Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.
Thanks to Randy Dunlap for doing many randconfig builds. And to Paul
Gortmaker for triage and bug fixes.

Cheers,
Stephen Rothwell

if I build with KFENCE=n it boots up eventually, here's my .config file [2].
Any idea what may happen?
it happens on next-20201109 also, but it takes longer until we get the
"Call trace:".

Hi Anders,
Does it happen during boot or afterwards?
10047 are seconds after boot, right? So this is like 3 hours after boot, no?
Also, is there anything useful before that part of the log? It seems
that at least the bug type header is stripped.

During boot, since it runs a lot of boot selftests.

No

This is a boot log where I actually get to the boot prompt.

oh I missed to say that this is the full boot log with the kernel
panic http://ix.io/2Ddv

Thanks!
The last messages before the hang are:
[ 1367.791522][ T1] Running tests on all trace events:
[ 1367.815307][ T1] Testing all events:
I can imagine tracing somehow interferes with kfence.
Alex, Marco, please take a look.
Maybe you will be able to reproduce it by enabling these boot tests.

The reason is simply that that config on qemu is so slow (enabling
lockdep helped), and the test that is running doesn't result in
allocations for an extended time. Because of that our wait_event()
just stalls, as there are no allocations coming in. My guess is that
this scenario is unique to early boot, where we are not yet running
user space, paired with running a selftest that results in no
allocations for some time.
Try and give that a spin:
