Kernel 6.16-rc4<\/strong> is out, and brief details are here: https:\/\/lkml.iu.edu\/hypermail\/linux\/kernel\/2506.3\/09013.html<\/a><\/p>\n

The latest NVIDIA driver 575.64<\/strong> compiles and loads\/runs OK but may fail when installed using the NV…..run file, but will be OK is installed manually, for some reason..<\/p>\n

UPDATE:\u00a0 NVIDIA 575.64.03<\/strong> is out, which seems to fix the need for manual compile etc…\u00a0 https:\/\/www.nvidia.com\/en-us\/drivers\/details\/249044\/<\/a><\/p>\n

VMware 17.6.3<\/strong> with the 6.15 patches and an additional VMMON patch\/hack will work… This patch has been hastily put together, based on the error message, and may be incorrect, but seems to work OK on my Fedora 42 system (Win10 Guest..)…<\/p>\n
