I have just upgraded my system from 7.2 to 8.0 using a source based upgrade. After rebooting it for the first time the server unfortunately failed to come back up. I had a look at the console and found that it was failing to find the root device and prompting me for it. By manually entering it I managed to boot the server and could then see the problem. In the 7.2 fstab my root partition and swap space were ad4s1a and ad4s1b but after booting the 8.0 kernel these seem to have changed to ad4a and ad4b so I set the new names in the fstab and it's now working fine. I read through the UPDATING file before I did this but I couldn't see any warnings that this may occur. The only entry that's possibly relevant is 20090320 talking about GEOM_PART. My question is is this change expected behavior or has my system done something strange? If it's expected then I think a warning could be needed for when more people decide to do this upgrade after 8 is released. Also I'm seeing a lot of messages logged to syslog saying "kernel: NMI ISA 3c, EISA 0" and "kernel: kernel trap 19 with interrupts disabled" over and over again. I commented out most of the usual debugging stuff from the kernel file whilst I was making my own kernel but these messages are obviously coming from somewhere else. Can somebody point me to what I need to change to disable these apparent debugging messages? Other than that everything is working well so far. Good work! Regards, Matt.
