Submission + - AMD confirms CPU bug found by DragonFly BSD's Matt Dillon (gmane.org)
An anonymous reader writes: Matt Dillon of DragonFly BSD just announced that AMD confirmed a CPU bug he found. Matt quotes part of the mail exchange and it looks like "consecutive back-to-back pops and (near) return instructions can create a condition where the processor incorrectly updates the stack pointer". The specific manifestation in DragonFly were random segmentation faults under heavy load.
