[Bug 1386597] Re: Oopses when ejecting thinkpad x230t from docking station with extern DP monitor

[Muelli]

So here is the result of my investigation.
It's a bit limited due to my limited time. I hope it is usefule nonetheless.

3.13.0-37 bad
3.18-rc1-utopic good

3.14.3 good

3.13.11.9 bad

3.14-rc5 oopses, but slow with backlight control
3.14-rc1 seems to work, but only coarse grained, other oops related to HID it 
seems
3.14.0 no oops, but very slow with the backlight control

3.15 very good

These are all the version I tested. Do you think it's worth testing
3.14.1 and 3.14.2?

FTR:
this is the 3.14-rc5 dmesg

[Christopher M. Penalver]

Muelli, the next step is to fully reverse commit bisect the linux kernel
in order to identify the fix commit. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

[Bug 1386597] Re: Oopses when ejecting thinkpad x230t from docking station with extern DP monitor

[Muelli]

yes, this kernel boots fine: Linux 3.18.0-031800rc1-generic
#201410192135 SMP Mon Oct 20 01:37:04 UTC 2014 x86_64 x86_64 x86_64
GNU/Linux

The backlight issue works much better now.
One thing I noticed is that when I redock the laptop, the backlight goes off. 
Increasing the backlight via the Fn+F9 key does not work immediately. It takes 
a few seconds before it accepts new controls.  This might, however, be caused 
by some scripts which react to the laptop being docked 
. I thought I removed them, 
but maybe there are still traces.

Anyway, I received this, which may be relevant:

Given that it works better, I'm adding the  kernel-fixed-upstream-3.18-rc1 tag

Muelli, would 3.18-rc1 allow you to boot and test to this problem?

[Bug 1386597] Re: Oopses when ejecting thinkpad x230t from docking station with extern DP monitor

[Christopher M. Penalver]

Muelli, thank you for reporting this and helping make Ubuntu better. Could you 
please test the latest upstream kernel available from the very top line at the 
top of the page (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 exactly 
shown as:
