I doubt it, this box has been running FreeBSD since 2.1.7. It had a long stint at 2.2.8. No problems. Then at 4.1 I started getting the resets and "falling back to PIO mode" messages. At 4.6 it just started panic-ing. If I back off to 4.4, no problems but the PIO message. If I boot a 2.2.8 floppy, no PIO warning. The error is correct, the chipset does not do DMA. PIO only. Even though it's set not to try dma in loader.conf it does. From my limited knowledge of C it looks like some value is not getting populated when the drive is probed, then eventually something references a pointer to that empty value and ba-boom.
