The following reply was made to PR kern/28616; it has been noted by GNATS.

I found a similar thing probing ata1 with quite different hardware (old P-100 system from a long-defunct manufacturer) with: disk on ata0-master CD-ROM on ata0-slave disk on ata1-master no ata1-slave I just put it down to errors in the ATA BIOS and learned to put up with it. If it turns out to be a real bug, I can happily send any relevent info.... Greg. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
