According to this post on the Intel community forums, a bug causing Skylake processors to freeze while running applications like Prime 95 has been fixed. Those of you running Skylake processors will have to update your BIOS once the fix is available from your motherboard manufacturer. Intel has identified an issue that potentially affects the 6th Gen Intel® Core™ family of products. This issue only occurs under certain complex workload conditions, like those that may be encountered when running applications like Prime95. In those cases, the processor may hang or cause unpredictable system behavior. Intel has identified and released a fix and is working with external business partners to get the fix deployed through BIOS.
