This time testing Ubuntu booted maybe once per 10 tries.

[penalvch (penalvch)]

Jussi Alanärä, thank you for reporting this and helping make Ubuntu better.

At your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[Jussi Alanärä (jusii)]

Tried the latest kernel Linux ft-desktop 4.4.0-040400rc6-generic #201512202030 SMP Mon Dec 21 01:32:09 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux and it made no difference.

Then started to go back and see which is the last kernel that always boots reliable, and that one seems to be

Linux ft-desktop 3.18.25-031825-generic #201512152250 SMP Wed Dec 16 03:52:48 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

around 30 succesful boots now, will leave it in reboot loop until tomorrow.

[penalvch (penalvch)]

Jussi Alanärä, the next step is to fully commit bisect from kernel 3.18 to 3.19 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your understanding.

[Jussi Alanärä (jusii)]

I'm a bit lost now, here's what I've done:

First tried bisecting vanilla kernel from linus tree and they seem to work just fine upto 4.4-rc7 so this is something Ubuntu specific. I tried also v4.4-rc7-wily from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and problem is still there.

I can't use git://kernel.ubuntu.com/ubuntu/ubuntu-wily.git because even the first kernel tag won't work so I backed to //kernel.ubuntu.com/ubuntu/ubuntu-vivid.git

I have git tags that I should bisect between and those are Ubuntu-3.18.0-13.14 and Ubuntu-3.19.0-7.7 which will list with: git tag command

But then I run into this problem (debian and debian.master directories missing) https://wiki.ubuntu.com/Kernel/KernelBisection#Why_did_the_folders_debian_and_debian.master_disappear.3F

and when I run
git rev-list Ubuntu-3.19.0-7.7 | grep $(git log --pretty=oneline -1 Ubuntu-3.18.0-13.14 | cut -d' ' -f1)
as suggested here https://wiki.ubuntu.com/Kernel/KernelBisection#Commit_bisecting_Ubuntu_kernel_versions_across_non-linear_tags

I get no sha1 so that suggests that tags aren't linear.

And from here I looked for the git tags http://people.canonical.com/~kernel/info/kernel-version-map.html

[Jussi Alanärä (jusii)]

Ok., got it.

And sure enough, by removing pinctrl-cherryview.ko Ubuntu will boot nicely even with the latest linux-image-4.2.0-22-generic

[Jussi Alanärä (jusii)]

I f I enable CONFIG_PINCTRL_CHERRYVIEW=m in 4.4-rc7 then it won't boot.

[Jussi Alanärä (jusii)]

And add to that comment from hackeron in here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521749

"It seems the following helps: BIOS > Boot > Boot Configuration > OS Selection > set Linux"

above holds true, if Linux is chosen in Bios, then pinctrl_cherryview.ko will load just fine and Ubuntu will boot.

[penalvch (penalvch)]

Jussi Alanärä, in order to engage Intel upstream, could you please test for this via drm-intel-nightly and advise to the results?

[Jussi Alanärä (jusii)]

Just tested with linux-image-4.4.0-994-generic_4.4.0-994.201512302100_amd64.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/ and same thing, won't boot.

[Jussi Alanärä (jusii)]

Looks like intel-gfx wasn't correct place. I'll follow info and instructions given there and will update here.

[penalvch (penalvch)]

Jussi Alanärä, as per the maintainer list, one would want to send TO Mika Westerberg, and Heikki Krogerus, CC linux-gpio.
