If I have a drive attached to my Promise PDC20269, it happens every time. If I remove the card and attach the drive to my motherboard's VIA 8233, it works just fine. It doesn't seem to matter whether I'm using either of the below drives on the Promise, the transfer just stops and eventually panics as described in the PR. The performance of the Promise is dismal, the Maxtor and the Seagate barely reach 20M/s throughput, while I get at least 50M/s on the VIA. There's something strange going on here. Motherboard is an ASUS A7V266/E. ad0: 76319MB <ST380013A> [155061/16/63] at ata0-master UDMA100 ad1: 57259MB <MAXTOR 6L060J3> [116336/16/63] at ata0-slave UDMA100 Hopefully Soren has an explanation. Maybe the VIA chipset doesn't get along with the Promise, although ASUS offered a Promise raid as an option on those boards (absent on mine). I've never seen any ATA error messages while using the Promise. To make a long story short, this appears to be an ATA problem, not a USB problem. Dumping filesystems to the USB drive worked before the NetBSD import, but the import probably exposed a completely different problem. It's safe to close this bug.
