[Bug 1407505] Re: No UMS support in radeon module
I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.
Can you test the following kernels and post back? We are looking for the
first kernel version that exhibits this bug:
v3.16.3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.3-utopic/
v3.16.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.4-utopic/
v3.16.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.5-utopic/
You don't have to test every kernel, just up until the kernel that first
has this bug.
Thanks in advance!

System: Kubuntu (adm64) 14.10.
Last update: 4-Jan-2015
No proprietary drivers.
No 3rd party software.
The last kernel I was able to run on my Utopic system is
3.16.0-17-generic. Every update thereafter failed. The last one I
tried is -28.

- I've tried regenerating /boot/grub/grub.cfg but there are no differences with previous file.
- The kernel command line is the same for both kernels.
