Looking at your screenshots, I'm getting plenty of these g_vfs_done() = 5 errors with an ordinary pen drive on various stages of stable/7 as well. The pen drive works flawlessly on other computers. Same for another pen drive I tried for verification. If you throw the EHCI driver out of the kernel your drive will use either OHCI or UHCI (both are slow). This seems to help, at least for the limited things I use this pen drive now. The good thing is, you obviously had a FreeBSD installation which worked fine with USB 2.0 drives. This would be a good starting point for the search of a fix. Any chance you can get back to that state? If the panics appeared without any change on the system, could you stress test this drive a little on another computer? MarKus - - - - - - - - - - - - - - - - - - - Dipl. Ing.
