>Description:
FreeBSD 9.0-RC1 boots into Multiuser on DockStar. A few seconds of disk I/O on USB mass storage devices later "USB error: address decoding error (addr=$HEX)" floods the RS232 console. They are stop as soon as all disk I/O is stopped. syslogd turns this into a feedback loop. (Nearly?) each log write results in new log messages. A "portsnap fetch" is enough on a fresh installation triggered the panic below.
console:
fb9ds# portsnap fetch
