Title:
kernel 3.16.0-28-generic breaks Radeon HD 6310
Status in linux package in Ubuntu:
Incomplete
Bug description:
When applying the updates on my Ubuntu Utopic installation I received the new
3.16.0-28 kernel.
The computer had no problems with the Utopic kernels before ( up to
3.16.0-26), but now it suddenly won't give any output (via HDMI) when booting.
I don't get X, I don't get a splah and I can't switch with ctrl+alt+fX to one
of the terminals.
When booting with the older kernels or the latest (3.18.0) kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/ no problem appears. I
also reinstalled the 3.16.0-28 kernel image and reran update-
initramfs, but the problem stays. So something explicitly in this
kernel is creating this issue.
Below I paste the relevant messages i found in the dmesg/syslog:
