BSD/Linux Kernel: ZFS, Intel, and AMD

University of Toronto ☛ The state of a filesystem is often unknown after write errors
The specific ZFS situation (also) is that when ZFS sent a write to the disk to make the directory creation durable, it got back an IO error. The general problem for any filesystem is that after a write IO error, the true state of the world is unknown and uncertain. This is true for writes in general, and it's especially true for writes involving filesystem metadata, especially the creation of something.

WCCF Tech ☛ Intel Razor Lake Gets Its First Linux Kernel Patch Ahead Of A 2028 Launch, With Desktop Chips Expected To Reuse Nova Lake-S’s LGA 1954 Socket
Intel is making some decent progress in delivering better support for its next-generation processors in Linux. Recently, the initial GCC patches for Coral Rapids were made, indicating support for AVX10.2, APX, AMX-FP8, AMX-AVX512, and several other advanced instructions, alongside the new AVX10_VPMLDSABFLYDQ, which aims to accelerate ML-DSA operations.

Video Cardz ☛ Linux 7.5 to fix video corruption on nearly 20-year-old Radeon GPUs
A Linux kernel update is set to address a video decoding issue affecting AMD Radeon graphics cards released almost two decades ago. The fix covers several GPUs from the Radeon HD 2000 and HD 3000 series, which debuted in 2007. It was developed with assistance from OpenAI’s Codex and is now included in the graphics updates proposed for Linux 7.5.

Tom's Hardware ☛ Nearly 20 years after launch, ancient AMD Radeon HD 2000 and 3000 GPUs finally get a Linux fix for corrupted video playback
A new kernel contributor used Hey Hi (AI) to develop a patch for the drivers powering his nearly-20-year-old Radeon GPU.
[...]
The culprit turned out to be a memory placement oversight: the driver wasn't consistently keeping UVD input buffers pinned inside dedicated VRAM. When graphics draw calls competed for resources, frames failed to decode properly. By forcing those buffers to stay in VRAM — a behavior the Radeon kernel driver apparently already enforced for several other chip families — video playback cleans right up.
