I found it a little while ago and am already doing a test build without weiping's test patch to see if that kernel provides what he(?) needs. Doing a rebuild with the test patch will go pretty quickly. So if I get the message with device_add_disk from these kernels, I should be able to get the information this afternoon. If there is some other reason I don't get that when I do the builds, I'm probably not going to be able to figure it out and get a build done before I leave. I don't live close enough to the office that I'm going to want to drive in just to be able to do a reboot test. (And my hardware at home does exhibit the problem.) If you have some other idea about why I might not be seeing the device_add_disk message, I'd be interested in hearing it.
