The patch is also here: http://people.freebsd.org/~rmacklem/kgssapi.patch I don't remember if you mentioned which kernel version you are running, but this would also be in stable/9 of about 6 weeks ago, but not in 9.1-release. If your system has this patch and still crashes, please email the backtrace for the crash. You can take a photo of it, if it is a screen console. rick > > Regards, > Elias
