Okay, so the breakdown for those following is: http://sites.google.com/site/tingox/f2-dmesg-8.0-stable-20100131.txt?attredirects=0 atapci0: <ATI IXP700/800 SATA300 controller> port 0xff00-0xff07,0xfe00-0xfe03,0xfd00-0xfd07,0xfc00-0xfc03,0xfb00-0xfb0f mem 0xfe02f000-0xfe02f3ff irq 22 at device 17.0 on pci0 atapci0: [ITHREAD] atapci0: AHCI v1.10 controller with 6 3Gbps ports, PM supported ata2: <ATA channel 0> on atapci0 ata3: <ATA channel 1> on atapci0 ata4: <ATA channel 2> on atapci0 ata5: <ATA channel 3> on atapci0 ata6: <ATA channel 4> on atapci0 ata7: <ATA channel 5> on atapci0 ad6: 238475MB <SAMSUNG HD252HJ 1AC01118> at ata3-master UDMA100 SATA 3Gb/s ad8: 953869MB <SAMSUNG HD103SJ 1AJ100E4> at ata4-master UDMA100 SATA 3Gb/s ad10: 953869MB <SAMSUNG HD103SJ 1AJ100E4> at ata5-master UDMA100 SATA 3Gb/s ad12: 953869MB <SAMSUNG HD103SJ 1AJ100E4> at ata6-master UDMA100 SATA 3Gb/s ad14: 953869MB <SAMSUNG HD103SJ 1AJ100E4> at ata7-master UDMA100 SATA 3Gb/s But the only ports which are having issues are ata5 and ata6, which hosts disks ad10 and ad12 respectively. SMART stats for ad10 and ad12 look fantastic, aside from slightly long spin-up times (claiming over 8 seconds), but that wouldn't cause what's seen here. Both disks have used for nearly 1700 hours. No SMART error log entries exist on either disk, which means the timeouts seen when speaking to the controller are very likely when talking to the controller itself (and not when waiting for the controller to submit a request to the disk and that piece stalling). I'm out of ideas aside from the following: 1) Disabling MSI/MSIX, which at this point I'm doubting will fix anything (but you never know), since I'd expect it to affect the entire controller and not just specific ports on the controller. 2) Replacing the SATA cables used between ata5<-->ad10 and ata6<-->ad12. 3) Getting mav@ to talk to AMD to find out if there's any AHCI quirks in the IXP700 or IXP800 SATA controllers, as there could be some weird driver bug/quirk on FreeBSD which is needed. Mainly for mav@: verbose boot messages for this system are here, in case any SATA register details are of help: http://sites.google.com/site/tingox/f2-dmesg-8.0-stable-20100131_verb1.txt?attredirects=0 http://sites.google.com/site/tingox/f2-dmesg-8.0-stable-20100131_verb2.txt?attredirects=0 -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
