=== System Hang with Vega Graphics (and select GPUs) ===

Currently on the latest kernel/mesa (currently 6.13 and 24.3.4 respectively), Vega integrated graphics (and other GPUs like the RX 6600<ref>https://bbs.archlinux.org/viewtopic.php?pid=2224147#p2224147</ref>) will have a possibility to hang due to context-switching between Graphics and Compute.<ref>https://bbs.archlinux.org/viewtopic.php?id=301798</ref> There are currently two sets of patches to choose between stability or speed that can be applied: [https://github.com/SeryogaBrigada/linux/commits/v6.13-amdgpu amdgpu-stable] and [https://github.com/SeryogaBrigada/linux/commits/v6.13-amdgpu-testing amdgpu-testing].

=== Sporadic Crashes ===

If getting error messages in <code>dmesg</code> with <code>page fault</code> or <code>GCVM_L2_PROTECTION_FAULT_STATUS</code> it might be from AMD GPU boosting too high without enough voltage

Use a tool like LACT to increase power usage limit to 15%, undervolt by moderate amount (e.g. -50mV for 7900 XTX) and optionally decrease maximum GPU clock.
