Developer Ingo Molnar said support for the 386 chip, which debuted back in 1985, meant complexity for developers who had to do more work to accommodate it.
"Unfortunately there's a nostalgic cost: your old original 386 DX33 system from early 1991 won't be able to boot modern Linux kernels anymore. Sniff," Molnar said.
Molnar is one of several developers working on the upcoming next version of Linux - version 3.8. Linux's version 3.7 debuted last Dec. 10.
