Dear developers,

I have a notebook that is giving me a lot of trouble, especially as it is the
newest computer that I have at my disposal where I can perform any actual work.

This notebook has VERY frequent lockups (hard freezes, where the screen
displays something where I am working, but the keyboard does not respond, the
mouse doesn't either etc.).

The only way that I can resume any work is by forcibly shutting it down (by
pushing the power button for many seconds) and, of course, having all previous
unsaved work lost (including a previous report of this bug with the bugzilla
interface). :-(

There is no particular pattern that I could discover so far that triggers the
problem (for the past year, at least), but I do see some error messages on my
dmesg logs and I would like start with some of the more salient points by
sharing some problems that I have and, perhaps, zero in on potentially loose
ends that may help everybody with hardware that is similar.

The notebook in question is a Dell Inspiron 5548 with a Core i7-5500U, with two
graphic cards (or so I am told), with one of them being integrated with the CPU
and another being a discrete AMD GPU.

The userspace that I am using is a Debian testing (soon to be Debian 10) with
Debian's kernel 4.18.0-2-amd64 (which is actually a kernel 4.18.10-2). I can,
of course, test any other kernels for the sake of getting things fixed. Just
let me know and I will do my best to fix things.

BTW, no kernel that I have ever used on this machine has every worked
perfectly, even the prebuilt, unpatched kernels that Ubuntu compiles daily.

With that being said, when the kernel boots up, there are some red messages on
the dmesg log that are related to this AMD GPU (the entire dmesg log will be
attached) with some prominent lines being:

Well, that's it. Please let me know whatever information you want me to get and
I will post it here.

Reiterating: I can compile kernels and or run other programs to diagnose
anything that you want me to to fix these issues.

Thanks in advance,

Rogério Brito.
