The following reply was made to PR kern/153205; it has been noted by GNATS. From: Alexander Motin <mav@FreeBSD.org> To: bug-followup@FreeBSD.org, lynx.ripe@gmail.com Cc: Subject: Re: kern/153205: [ahci] PIONEER DVD-RW: timeout with ahci(4), OK with ata(4) + ATA_CAM Date: Thu, 28 Apr 2011 21:49:51 +0300 Hi. As I can see from dmesg, controller reports that command is completed, but driver either haven't received interrupt or mishandled it. Just an idea, could you try to disable MSI interrupts for the controller by setting hint.ahci.0.msi=0 in /boot/loader.conf? -- Alexander Motin
