Hi, I've updated a server with mpt controller to the latest 7-stable (ok, it's 7-stable from last week). During the boot sequence, the disk connected to the mpt controller (da0) seems to be probed too late, i.e. just _after_ the kernel tries to mount the root file system. It's just a fraction of a second too late. This is a screen shot of the situation: http://www.secnetix.de/olli/tmp2/screenshot-boot.jpg Of course, I can enter "ufs:da0s1a" at the rootmount prompt, and the machine continues to boot fine. But this is a server that should be able to boot unattended, so I need this to be fixed. What's the "official" way to fix this? I think someone else had a similar problem some time ago, but a quick search of the lists doesn't yield anything. (BTW: Interestingly, the same machine boots fine without hickup when booting 8-stable which is installed on another Slice of the same disk. This could be just coincidence, maybe the timing of probing is slightly different between 7-stable and 8-stable.) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
