Architecture: i386
Machine: i386
>Description:
I am trying to update a machine running 1.5 to -current, but the new ahc
driver causes a panic whilst going multi-user. I've tried using
AHC_NO_TAGS, but that doesn't make any difference.

The following was captured with a serial console - it contains dmesg
information from both a good, 1.5 boot, and the information from booting a
1.6W kernel, along with a 'bt' from the ddb prompt.

>How-To-Repeat:
Build new kernel including ahc, boot new kernel
>Fix:
Unknown
