Public bug reported:
My PC froze inexplicably while I was using it and the loading (stuck) mouse
pointer was the only thing that moved.
I was ending to watching the WWDC from VLC.
It happened some night ago around 00:15, I would provide different details of
this issue I could send if only know what it needs, so please let me know what
I can do.
When the freezing happened I tried to press some combinations of keys (like
ctrl + alt + f3, etc.), opened and re-opened the laptop to try the suspension
but nothing happened so I pressed the power button.
I checked my last journalctl sessions (journalctl --list-boots) and I
found this session:

[AMD/ATI] Wrestler [Radeon HD 7310] [1002:9809]
I tried to send these messages to ChatGPT and it makes me a summary of
what it "thinks" it's the problem:
During normal desktop use (Unity session), the system completely froze
without any possibility of recovery, including switching to a TTY
(Ctrl+Alt+F3). The logs clearly indicate a crash in the graphics
subsystem related to the AMD Radeon HD 7310 using the radeon driver. In
the minutes leading up to the freeze, there are repeated DRM errors
related to video decoding (UVD) and command stream handling, in
particular “invalid command stream” and “reloc crossing 256MB boundary”.
Shortly after, the kernel reports a GPU lockup (ring 0 stalled),
followed by attempts to perform a GPU soft reset, which only partially
succeed. At the same time, user-space applications such as the Brave
browser lose their GPU context and restart their graphics pipelines,
indicating a forced driver reset or loss of GPU context. Overall, the
issue does not appear to be a general system crash, but rather a hang in
the radeon driver on relatively old hardware, likely triggered by
hardware video acceleration. The GPU reset occurs but is not sufficient
to restore the graphical session, which remains completely frozen. As a
possible hint, this seems consistent with instability of the radeon
driver’s UVD path on legacy GPUs, where video decoding or 3D
acceleration can trigger a full ring buffer lockup leading to a complete
desktop freeze.
