The hard disk in a mac mini is rather slow, so I have freebsd installed on an external firewire drive. The way it's setup, all the filesystems (including '/') are on that external firewire drive. This has been working okay for awhile. This past Sunday I updated my 7.x source tree and compiled everything. When I tried to boot up with the new kernel, I hit a panic: trying to mount root from ufs:/dev/da0s9 panic: ds_len > SBP_SEG_MAX, fix busdma code KDB: enter: panic At the time I was already running late for something else, so I just rebooted into the old kernel and went back to running that. The older kernel was compiled on May 30th. The check I ran into is in sys/dev/firewire/sbp.c , and has been there for years, so it isn't a new check. Has anyone else seen this? -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
