The following reply was made to PR alpha/75317; it has been noted by GNATS. From: Nathan Whitehorn <nathanw@uchicago.edu> To: bug-followup@FreeBSD.org, hadarai@bsd.ee Cc: Subject: Re: alpha/75317: [ata] [busdma] ATA DMA broken on PCalpha Date: Tue, 07 Mar 2006 16:24:43 -0600 This occurs on my 164SX running 6.1-PRERELEASE and can be reproduced on 6.0-RELEASE and 5.4-STABLE as well. None of the above patches fix the problem on 6.0. With ATA drives in the system, and DMA on, machine checks occur every few hours at best, every few minutes at worst. With the same drives attached by firewire, I haven't had a single machine check ever.
