Bug description:
I've got an Acer Aspire V5-551G with a 64-bit AMD processor with dual boot,
Windows 10 and Ubuntu 16.10.
Ubuntu can be started and runs without problems with Linux kernel 4.4.0-45.
When I try to start with any of the 4.8.0 kernels delivered with regular
Ubuntu updates, they all hang after printing
Läser in Linux 4.8.0-34-generic ...
Läser in initial ramdisk ...
Sorry for the partly Swedish text. I guess that the lines would start with
"Loading" instead of "Läser in" on an English version.
The behaviour is the same with all 4.8.0 versions up to the latest 4.8.0-34
and with -generic, -generic (upstart) and -generic (recovery mode).
After a while the fan runs at full speed, as if the processor is working
hard, but nothing happens.
After I've tried in vain to start with Linux 4.8.0-xx, and then starts
with 4.4.0-45, the following errors are usually printed:
[ 2.511733] usb 4-3: string descriptor 0 read error: -22
[ 3.841872] [drm:radeon_scpi_init [radeon]] *ERROR* Cannot find backlight
controller
/dev/sda7: clean, 807007/9363456 files, 7364300/37423360 blocks
[ 21.335117] usb 4-3: string descriptor 0 read error: -22
When a successful start has not been immediately preceded by a failed start,
only the line beginning "/dev/sda7" is printed.
I have previously commented on bug #1635447. As recommended there, I've
also tested with the upstream kernel 4.10-rc3. It worked just as bad as
4.8.0.
I tried to report this bug with 'ubuntu-bug linux' after I had booted with
the 4.4.0-45 kernel, but I couldn't. It said that linux-image-4.4.0-45-
generic is not an official Ubuntu package.
