While the first good commit isn't applied downstream (in order to fix
previous kernel versions), I currently recommend using stable kernel
4.7.4, available at http://kernel.ubuntu.com/~kernel-
ppa/mainline/v4.7.4/
There are newer stable kernel versions available, but I haven't tested
them. I can c
I'm with a Dell Inspiron 5447 (Radeon R7 M265) and just updated my
system, now It's using the kernel 4.4.0-45-generic and the problem is
still happening. My system is crashing entirely if I log out from my
user, for example.
I know I can fix it by using a newer kernel package from Mainline but i

@Timo Aaltonen (tjaalton): after reading your comment, I decided to
install kernel 4.4.0-23.41, but it isn't available on the repo anymore,
so I installed kernel 4.4.0-24 (if "that revert is already in the xenial

Note: on that entire PDF table, I used "good" meaning "has bug" and I

Hello.
It took me some days and 26 kernel compilations, but I finally found the
first good commit. I thought kernel 4.6-rc1 carried the first good
commit, but it turns out it also had the bug: the first commit is in
kernel 4.6-rc4. Here's the output of my last RCB (reverse commit bisect)
report:
Yuri Ribeiro Sucupira, the next step is to fully reverse commit bisect
from kernel 4.5.7 to 4.6-rc1 in order to identify the last bad commit,
followed immediately by the first good one. Once this good commit has
been identified, it may be reviewed for backporting. Could you please do

@Christopher M. Penalver: I've just read comment #26. Ok, I'll test a
little more to confirm if v4.6-rc7-wily really fixed this bug and, if it
