An AthlonXP 1600+ (Palomino). Would this really impact on the stability of the USB 2.0? If that's a possibility, I have an Athlon 1GHz CPU that I used to run very well with a KT133 board and an NEC USB 2.0 card that I can test on the same motherboard. >That seems likely to be some > kind of misconfiguration.

I wouldn't be surprised either, but considering this message was being displayed almost immediately after ehci-hcd had been loaded, I thought it was worth mentioning. > > 00:10.3 is the VT8235's USB 2.0 controller.

I'm not sure if it would help, but here's the exact numbering on my VT8235: VT8235 0244CD TAIWAN 23A3486641 >if you haven't been seeing lost IAA statistics when you > "rmmod ehci-hcd", like "(lost 223)", that'd be my guess as to why > our results seem different. After unloading ehci-hcd, there were some messages. After copying 530Mb of files to the USB 2.0 HDD: ehci-hcd 00:0a.2 (NEC USB 2.0 Unused): irq normal 0 err 0 reclaim 0 (lost 0) ehci-hcd 00:10.3 (VIA USB 2.0 Used): irq normal 158604 err 1 reclaim 11330 (lost 102) I then cold booted the computer and copied 70Mb from the USB 2.0 HDD to the IDE HDD (more than that usually causes the system to hang): ehci-hcd 00:0a.2: irq normal 0 err 0 reclaim 0 (lost 0) ehci-hcd 00:10.3: irq normal 20339 err 1 reclaim 2517 (lost 11) Does this mean anything?
