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

 

Cut from Bug Description.

** Tags added: latest-bios-2.60

** Attachment added: "log.txt"
   https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1386597/+attachment/4247119/+files/log.txt

** Description changed:

- With an earlier version of the kernel I noticed that the backlight was
- not working properly when ejecting the laptop from the docking station
- <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1308674>. Now,
- with this version, everything seems to work well, but I do get Oopses in
- dmesg.
