I tested daily-live of March 19. I don't get any AMDGPU *ERROR* and
suspend is as expected so I think this bug has been fixed.
So what about current 16.04 LTS ? For now I'm using kernel 4.10 but I
have to manually update it.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed

Title:
AMDGPU causes kernel panic with
Status in linux package in Ubuntu:
Confirmed
Bug description:
Laptop is Toshiba Satellite S50-B-12R
http://www.toshiba.be/fr/discontinued-products/satellite-s50-b-12r/
Graphic card is AMD Radeon R7 M260
Running Ubuntu 16.04, system was unstable when first installed it (a
lot of random kernel panic). Problem seemed related to new AMDGPU
drivers introduced into new kernels so I tried to disable graphic card
by adding radeon.modeset=0 to GRUB_CMDLINE_LINUX_DEFAULT as suggested
here http://askubuntu.com/questions/771562/16-04-power-off-discrete-
graphics-ati-amd and there
http://askubuntu.com/questions/771838/should-i-disable-amd-graphic
After this, system is stable except when sleeping. After wake up, I
get a kernel panic within 5min (time is random). System logs show a
trouble about AMDGPU *ERROR*.
WORKAROUND: Do not disable switcheroo and add to GRUB_CMDLINE_LINUX_DEFAULT:
radeon.modeset=0 amdgpu.runpm=0 acpi_backlight=intel_backlight
WORKAROUND: Use the Intel integrated graphics card.
