Aside from my own concerns, I thought it might be useful for others to know, as the LOR's were produced by the kernel installed from the distribution media (disk 1). Also, in the event I'm not the *only* one experiencing these LOR's. It might be nice replace the kernel that's currently on the media, with one that won't do this. As I imagine many who install FreeBSD from the media, might never build their own. The sysctl/tunable sounds like a real winner. :) Thanks for taking the time to respond, John. --Chris > > -- > John Baldwin > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
