Ubuntu randomly freezes

[GLEPIN Cyprien]

Ubuntu randomly freezes, sometimes after 30 minutes, sometimes after 3h, sometimes not at all.
I don't know what it can come from, I think it's PHP 7.2 or Nvidia drivers but I'm not sure.
I've a AMD Ryzen, perhaps it's here ?...

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
