--- Comment #80 from Allan <allan4229 at gmail.com> ---
Closing this issue, here is the summary for a quick look:

The problem : amdgpu hangs suddenly, nothing can kill it.

Solution : The driver got more stable over time.

The causes :
1 - The driver itself was more unstable.
2 - The kernel wasn't supporting ryzen CPUs properly, leading to segfaults and
unexpected behaviors. If it is your case, use any kernel already listed here.
3 - Corsair RAM is not a good deal to work with Ryzen, specially if they don't
have some kind of "Ryzen ready" seal. Aiming the best performance for Intel
platforms made them to not support JEDEC standards properly while trying to use
the SPD profile, even if you try to delay latencies.
Thus, bad RAM -> unexpected behaviors, including from the driver.

Additional information :
I was able to test only a few days (a week or so) before the GPU showed BGA
problems.
It was working fine.

If I ever be able to test it again and find another scenario where the driver
hangs and can't be killed I'll report here.
