The following reply was made to PR kern/80042; it has been noted by GNATS. From: Marc Flambard <marc-pub@sarambard.homedns.org> To: bug-followup@FreeBSD.org, nobody@junk.com Cc: Subject: Re: kern/80042: FreeBSD 5.4 RC2: Promise PDC20265 on A7V mobo + Maxtor 6B200P0/BAH41BM0 gives only 268435455 instead of 398297088 sectors Date: Mon, 06 Jun 2005 18:46:44 +0200 I have the same problem with Promise PDC20265 on K7T266Pro2RU and 200Go disk but just on second channel (maybe the same for you). It's a LBA 48 bits access problem on second channel. After applying you're patch (just on ata-chipset.c) on FreeBSD 5.4, everything work fine for me. The test on channel in case of 48 bits access (ch->unit ? 0x24 : 0x20) solve the problem. Today i use FreeBSD 5.4 on K7T266Pro2RU (Promise PDC20265) whith RAID0 2x200Go bootdisk.
