[no OC] After installing mobo Gigabyte GA-F2A68HM-H and APU AMD A10-7850k (Radeon R7), Windows and Linux started random rebooting (usually in less than 2 minutes after booting) after I installed the recommended Radeon drivers (I tried the last version from this month for Windows).
I couldn't find any other kind of correlation (for instance, I tried stressing the CPU/memory to see if it rebooted quicker).
With the default (generic) driver it works flawlessly (both in Windows and Linux) - but, of course, some features are not available (especially related to games)

Any ideas if this is a mobo or APU issue?
Thanks

Check for grounding issues one more time, then call AMD technical support. It could be a weird firmware issue, a bad card, BIOS/UEFI - or possibly something else. In generic graphics mode the graphics card should actually be doing very little, so when you activate the driver, you could be in effect turning on a bad card (or chip, piece of firmware, etc). If you have a spare computer somewhere, you can see if the card works with that. Also, BIOS implementations have always been notoriously finnicky, and I kind of doubt UEFI is much better (I run a BIOS system that has GPT compatibility, so I don't have firsthand knowledge of UEFI only systems). If there is something about your BIOS or UEFI that is not sane, it's always possible that...

This could be BIOS or UEFI, could be the card itself, or it could be a short - check all the grounds, make sure theres no little floating metal pieces or hanging wires, etc. One thing you can do in Linux, if you're able to get to a console screen: boot from a liveUSB so you'll have USB already mounted on boot (make sure the LiveUSB permits this), and then quckly log in and 'dmesg > dmesg.txt'. Unfortunately you won't have the dmesg colored output, but you'll be able to comb through it carefully looking for issues. I would check for bad grounds first.

And yes, you could have shook the machine around the time you installed the new driver, so there's no absolute correlation there, and I see no reason that windows drivers would be rebooting Linux.

Windows driver is not impacting Linux.

Running Windows with generic graphics driver: no issue
Running Windows with Radeon R7 driver: random reboots (Windows)

Running Linux with generic graphics driver (ati): no issue
Running Linux with Radeon R7 driver (catalyst): random reboots (Linux)

I tried going from generic to proprietary and reverting a couple times and the above scenario happens everytime.

If there is something about your BIOS or UEFI that is not sane, it's always possible that activating a new piece of hardware could trigger it. Don't assume the BIOS/UEFI is sane out of the box either - go over it line by line and look for things that could be wrong.

Also, did you try the dmesg thing like I suggested? If you did, go ahead and post it up on a pastebin somewhere and post the link here. Linux is usually *quite* good at detecting hardware/firmware errors.
