Hi, I've Problems with the ATA driver in 4-STABLE (cvsupped the source today, but the problem exists for me since back to 4.6-RELEASE as far as I remember). The driver is doing a fallback from UDMA66 mode to PIO4 mode on my Promise Ultra66 controller. (On the onboard controller of my mainboard [UDMA100] and on my HighPoint UDMA66 controller this does not happen). Here are the messages I receive: Aug 22 14:05:56 interruptus /kernel: ad8: READ command timeout tag=0 serv=0 - resetting Aug 22 14:05:56 interruptus /kernel: ata4: resetting devices .. done Aug 22 14:06:06 interruptus /kernel: ad8: READ command timeout tag=0 serv=0 - resetting Aug 22 14:06:07 interruptus /kernel: ata4: resetting devices .. done Aug 22 14:06:16 interruptus /kernel: ad8: READ command timeout tag=0 serv=0 - resetting Aug 22 14:06:16 interruptus /kernel: ata4: resetting devices .. done Aug 22 14:06:26 interruptus /kernel: ad8: READ command timeout tag=0 serv=0 - resetting Aug 22 14:06:26 interruptus /kernel: usb1: scheduling overrun Aug 22 14:06:26 interruptus /kernel: usb0: scheduling overrun Aug 22 14:06:26 interruptus /kernel: usb1: scheduling overrun Aug 22 14:06:26 interruptus /kernel: usb0: scheduling overrun Aug 22 14:06:26 interruptus /kernel: ad8: trying fallback to PIO mode Aug 22 14:06:26 interruptus /kernel: ata4: resetting devices .. done Aug 22 14:06:36 interruptus /kernel: ad8: READ command timeout tag=0 serv=0 - resetting Aug 22 14:06:36 interruptus /kernel: ata4: resetting devices .. done The machine was booted 25 minutes ago, and I was listening to some music from this hdd via samba 2.2.5 on my windows box... I had this behaviour quite often in the last days: booting, ata-driver in UDMA66 mode and then after some time using the hdd a fallback to PIO4... I would say it's not a cable-problem, because I checked my cables and run the same configuration on the other controllers where all seems ok. here is my dmesg output: Copyright (c) 1992-2002 The FreeBSD Project.

the ata stuff and perhaps finds more infos for my problems. ah, btw, my ata-settings: obie@interruptus$ sysctl hw | grep ata hw.ata.ata_dma: 1 hw.ata.wc: 0 hw.ata.tags: 0 I tried hw.ata.wc=1, too, but it has nothing to do with the problem (I get READ timeout, not WRITE timeouts) Ok, I think thats it..
