Perhaps it is time to send your 37-year-old Intel 486 system into retirement, as far as modern Linux goes, as OS kernel developers appear to have started to dismantle support for this legendary CPU. Phoronix reports that the change seems to have been confirmed in patches destined for the Linux 7.1 kernel. So, those still cherishing their 486 PCs and using them to run a modern version of Linux should probably now make sure they run one of the existing Linux LTS kernels to squeeze a few more years from the platform. Alternatively, they could upgrade to a Pentium or even one of the best CPUs available in 2026.
The patching out of 486 support isn’t really a surprise. Firstly, it is ancient, with the first examples released in 1989, and modern Linux distros continue to grow more resource-hungry. Secondly, Linux creator Linus Torvalds hinted not long ago that 486 support may get the axe. The Linux mogul said that there was “zero real reason” to continue support for the 486 CPU. In fact, he indicated that continuing support for it was detrimental to upstream Linux kernel development efforts.
