1002:9830 [HP Pavilion 15-e010ax Notebook PC] Unable to install Saucy

[brianM]

Tried to install U13.10 using the desktop installer on HP 15e010ax laptop. Goes thru splash screen to freeze with a black screen with no cursor. Unable to access terminal. Was using uefi boot with secure boot disabled. This is a regression as U13.04 works on this machine and has been used to gather the debug info attached due no terminal access in 13.10. This occurs when trying to boot to live session or straight to install. Appears installer cannot set up a satisfactory default video driver for this machine. Note VESA: KALINDI works on 13.04 and probably should in 13.10.

WORKAROUND: modprobe.blacklist=radeon

WORKAROUND: I installed saucy in this machine by a partition copy from another working pc. Found that a recovery boot works and installs video driver vesa:kalindi. Also installing fglrx works.

Just to clarify the ISO will be Trusty and the Mainline Saucy?

Issue remains exactly the same in latest daily dev release iso (trusty)

[brianM (brian-openitca)]

see bug 1253535 for info on a driver issue which may be linked.
Also for apport info from saucy on target machine (prev appport was raring)

[brianM (brian-openitca)]

ok but will be early next week before I can get back to this
cheers brian

Chris
This is new to me so I need some help. I am to bisect using deb kernel
packages between Raring and Saucy? Not sure where to find these. Also if
using just kernel updates I can't test the installer so testing would
only involve seeing whether a default video driver can be successfully
installed?
Thanks Brian

I have 3.11.0-14 installed in Saucy which freezes with the default
driver but works with fglrx. Also have Raring installed with 3.8.0-34
which works with the default driver. I tried the later kernel in Saucy
and it freezes. Can't see any kernels in between these two in your
references?

I also noted the following message before freeze in Saucy
- failed to find a backlight controller
which doesn't appear when using the fglrx driver

oops - I should have said I tried 3.8.0-34 in Saucy and it worked

The problem is between 3.9.0-7 and 3.10.0-0. There is a boot to GUI in the
first with vesa-kalindi driver and only to a command line in the later. I
have attached dmesg output for both. The following lines in 3.10.0.0 appear
to be relevant

It fails at v3.10-rc3.
Note that in the failed kernel tests it boots to a low graphics option
screen (after the radeon error in my prev post) and then a terminal is
possible. In the original bug, based on the Saucy installer, no terminal is
available.

I have got to a point where kernels will not boot on my laptop due to a
different issue (locks at loading ramdisk).
What I have now is

e748a38596932af8632448f35e8b2bba714ae03d bad
fffbdda4eee69f99b8c798d8eaca91c7e0513f08 good

a4eeea4e530fee26918529eb1b36ae306095eef5 fail at ramdisk

Is it necessary to continue trying to find bootable kernels between the
good and bad

brianM, thank you for commit bisecting this issue. One more thing before this is marked Triaged, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

[brianM (brian-openitca)]

Tested with v3.13.0-031300rc3_3.13.0-031300rc3.201312061335 and it still

brianM, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream ?

Please provide a direct URL to your post once you have made it so that it may be tracked.

Thank you for your understanding.

[brianM (brian-openitca)]

do I send to the drm or radeon maintainers?

brianM, I would send it to both mailing lists (DRM DRIVERS and RADEON FRAMEBUFFER DISPLAY DRIVER), and CC both Alex Deucher <email address hidden> and Christian König <email address hidden> .

[brianM (brian-openitca)]

Have sent email to addresses as suggested. Will I receive info with a
url as you requested or do I need to subscribe to these lists

After some emails with Christian König he seems to think it is a ubuntu problem. Not sure how this is fed back to ubuntu developers?
Also a workaround was tested successfully - setting on the kernel command line "modprobe.blacklist=radeon"

[brianM (brian-openitca)]

Still no gui boot in Trusty release with the desktop installer - but with some variations. This time access to a terminal is possible. The workaround I used was to boot with the nomodeset parameter which gives a gui and then do a full install and also install the fglrx driver. This gives a working system.

brianM, it would seem that the linux-fbdev mailinglist is not the correct outlet to seek upstream support for this problem. Given it's Radeon driven, you may want to create a bug report on freedesktop.org following http://dri.freedesktop.org/wiki/Radeon/ (kernel graphics upstream would be the exception to kernel upstream as this is their preference for verified bugs).
