I finally took the plunge this weekend and did a clean install on my system using 2.2-960501-SNAP, and I built a custom kernel. There weren't any problems with the aic7xxx driver that I had seen when I was using 2.1-960505-stable; the system booted several times without a problem. Then I sup'ed -current and did a make world, plus a kernel recompile using the same kernel config file I had used with -SNAP. The builds went fine. However, the new kernel won't boot; it hangs on my 4mm DAT drive and CD-ROM, tries several other non-existent targets, and later panics. Unlike with -stable, it happens every time. The relevant differences from the dmesg log, and the versions of the files, appear below. I saw the message on one of the mailing lists with the patch to two of the driver files, so I applied it, and things were worse: it hangs on the first device (a disk drive). Differences from that boot's dmesg are also below. As a last resort, I tried restoring just the eight aic7xxx driver files from -SNAP into the -current /usr/src/sys and remaking the kernel. It hangs essentially the same way as the unpatched -current aic7xxx kernel. The -SNAP kernel still boots (although things like the -current ps don't work), but the -current kernel (with either -SNAP or -current aic7xxx) doesn't. Any ideas, or other things I need to provide to help troubleshoot? Thanks!
