It was just earlier this week that Mesa 25.1.2 arrived as the newest bi-weekly bug-fix release for these open-source OpenGL and Vulkan drivers. Coming out today is an emergency bug-fix release to fix a regression affecting AMD Radeon RX 9000 series RDNA4 graphics card owners.
A bug crept into the Mesa 25.1.2 release that caused show-stopping problems with AMD RDNA4 GPUs. Samuel Pitoiset of Valve landed a change in Mesa 25.1.2 to try to mitigate a HiZ GPU hang by increasing a tineout. That mistakenly ended up causing a nasty RDNA4 regression in that release.
With Mesa 25.1.3 comes this partch to fix emitting the UPDATE_DB_SUMMARIZER_TIMEOUT on GFX12 (RDNA4) since it turns out not all PPP firmware for GFX12 GPUs have this packet.
In turn for those on affected firmware with an RDNA4 graphics card found an instant crash on upgrade to Mesa 25.1.2. Multiple users were affected by this issue and the new patch that makes up Mesa 25.1.3 is confirmed to fix the problem by having an appropriate firmware check.
So if you are using an AMD RDNA4 graphics card, be sure to grab Mesa 25.1.3 for this fix affecting the RADV and RadeonSI drivers.
