Hmm, ok. > Problem of ALI SATA is a bit different.

I will just fix the ALI attachment to handle this possibly by using 'chipset_data' to cache resources. -- John Baldwin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
