I put a 2MB caching Promise IDE controller into my 486 and moved the drives off the onboard IDE controller that this motherboard supports. I disabled the BIOS settings for the onboard IDE, then restarted. Under a current kernel built just two days ago, it fails to find wdc0 at 0x1f0, can't mount /root, and panics. If I go back to my previous kernel built August 8, it can find it just fine (which is what I'm using now) and 0x1f0-0x1f7 irq 14. So something has changed in the probing at startup that is causing it to miss the drives hanging off this older caching controller.
