Greetings, I just installed an ALi based USB2.0 in an effort to avoid the disconnects I've been having with my mobo's VIA chipset. The performance of the new board is awful -- 8 to 12 minutes to copy 1GB to an external hard drive, compared to approx 50 seconds for the VIA. vmstats shows that the writes/second will be OK for a while (a thousand plus per second), then goes to 0 for 20 or 30 seconds. /var/log/messages shows:

Anybody have experience with the ALi chipset (specifically on a StarTech.com USB 2.0 4 Port PCI card)? Thanks.
