The following reply was made to PR kern/21139; it has been noted by GNATS. From: "Justin T. Gibbs" <gibbs@plutotech.com> To: campt@miralink.com Cc: freebsd-gnats-submit@FreeBSD.ORG Subject: Re: kern/21139: IBM DNES drives need 'quirk table' entry. Date: Fri, 08 Sep 2000 16:16:03 -0600 >IBM DNES drives do not support more than 64 tagged queued commands and >the default settings for maxtags is 255 which is problematic. Under heavy >write loads this leads to a system crash. The problem here is the system crash, not that the table starts out your drive with a tag count of 255. CAM should automatically reduce the count to the maximum supported by the device. Can you give some details about the panic you are seeing? -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
