Greg et al, I added "flags 0x80ff" to my wd0 and wd1 lines (I don't have PCI IDE, but rather VLB, so the 0x4000 bit doesn't apply) :), was able to successfully get 32-bit mode and multiblock-16 out of both of my drives, and have been able to enable softupdates all around again without seeing any of my problems either. (I did re-cvsup -STABLE just before the kernel rebuild and did config -r to make sure everything was cleared out -- my old kernel was from the 20th, I believe.) My previous test was simple -- tar zxvf samba-2.0.0.tar.gz. :) Just to see if maybe it was just because it was being faster, I also concurrently ran a chflags -R noschg /usr/obj;rm -rf /usr/obj on the same partition. I did see somewhat "pausy" activity, but it didn't actually hang. Now, we just have to figure out why 32-bit-mode is so special. :) I have access to a few other boxes; I'll get those set up and see what we can see.
