Linux 6.15-rc4 To Fix The Kernel Crashing For 32-bit Systems With Too Much RAM  Phoronix

With the Linux kernel now limiting 32-bit systems to 4GB of memory even with the "HIGHMEM" Kconfig option, an issue was uncovered where if the system was still populated with more memory than addressable by 32-bit systems, the kernel would crash. With the Linux 6.15-rc4 kernel due out on Sunday, this issue will be addressed...

Intel 200S Boost Performance Mode Benchmarks On Linux  Phoronix

This week Intel announced "200S Boost" for Core Ultra "Arrow Lake" K-Series desktop processors as effectively a new overclocking profile rolling out to existing Z890 motherboards via a BIOS update. Enabling the 200S Boost profile is said to help with low-latency workloads like gaming by allowing higher fabric / die-to-die / memory frequencies. While some Windows benchmarks have begun emerging for the Intel 200S Boost mode and some limited gains, I was curious about the performance under Linux so here are some 200S Boost benchmarks with the Core Ultra 9 285K on Ubuntu 25.04.
