The Intel Pentium D is a very old processor, and its hyper-threading is very different from the recent processors.

We do ship some public microcode updates for several Pentium D processors, but they're really old updates. There is no guarantee that they will fix your issue. Note that it could be a problem elsewhere. Those are old processors, in old motherboards, with old system components (memory, power supplies, etc). And the current software (kernel, etc) is not often tested on them anymore, so it could be a software problem, too. If you want to try, please install intel-microcode as described in https://wiki.debian.org/Microcode Pentium D specification updates ("defect list"): https://www.intel.com/content/www/us/en/support/processors/desktop-processors/000007016.html http://www.intel.com/content/dam/support/us/en/documents/processors/pentiumd/sb/310307.pdf http://www.intel.com/content/dam/support/us/en/documents/processors/pentiumd/sb/306832.pdf -- Henrique Holschuh
