Upgrading from the stable 1.5 firmware image to initially 1.7.5 beta 1, I've been getting error messages on startup and shutdown . Startup might just be scanning the system each time and giving on-screen feedback, but I get 2 lines of errors each time I power off. I've upgrades to 1.7.5 beta and today (while it was available) 1.7.7 and still see the same issue (although 1.7.7 did build a swap file on initial startup unlike the previous ones)
