I also get this when booting - think it started happening when I started using the new ata-driver. For me it happens when the root is supposed to be mounted (from dmesg): <snip> atapci0: <Intel PIIX3 ATA controller> port 0xffa0-0xffaf at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 <snip> ad0: 2015MB <ST32132A> [4095/16/63] at ata0-master using WDMA2 ad2: 814MB <Maxtor 7850 AV> [1654/16/63] at ata1-master using PIO3 acd0: CDROM <CD820E.0v1098300> at ata0-slave using PIO3 Mounting root from ufs:/dev/ad0s1a ad0: READ command timeout - resetting ata0: resetting devices .. done ad0: READ command timeout - resetting ata0: resetting devices .. done ad0: READ command timeout - resetting ata0: resetting devices .. done ad0: READ command timeout - resetting ata0-master: WARNING: WAIT_READY active=ATA_ACTIVE_ATA ad0: trying fallback to PIO mode ata0: resetting devices .. done and then everything proceeds as normal. > I dont get any panics or anything, and after the reset to PIO everything > seems to work fine. agree. > ad0 is an IBM Deskstar 22GXP.

If there is something I can do to fix this I'm all ears. There are probably many people out there affected by this so I really think it ought to be fixed - preferably before -RELEASE. -- Patrik Sundberg - email: ps@raditex.se || ps@radiac.mine.nu ---> telefon: 013-178 567 - mobiltelefon: 070-760 22 40 <--- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
