I had some CAM errors too but I hit the reset button and it went away - I think the controllers just fail to initialize sometimes, maybe static buildup or capacitance or something. Its weird, as I haven't had it happen for ages but saw it for the first time yesterday after upgrading. I'll keep an eye on the console messages and see what happensScale (alpha) seemed to install properly (booted but not fully operational). RC1 fresh install declared success but system is having trouble booting (lots of CAM errors & failing to find boot pool). I think there may be a compatibility issue between the MB, the USB-SATA case chipset, & the OS. I plan to take no furhter diagnostic actions until release but am open to suggestions, as always. Seems like that system could stay at 11 until it dies.
