** Description changed: 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.

I checked my last journalctl sessions (journalctl --list-boots) and I - found this session: - - dinosauro-trex@dinosauro-trex:~$ journalctl -b -2 -e giu 09 00:14:18 - dinosauro-trex wpa_supplicant[759]: nl80211: deinit ifname=wlp2s0 -

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. I tried to speak with a maintainer of Ubuntu Unity and it says me: "it looks like radeon driver has some bugs or even the GPU can sometimes have hardware bugs (which is normal, it doesn't mean that the hardware is faulty)."

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 the session I described in log.txt + (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2156440/+attachment/5976875/+files/log.txt) 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.
