Hi Alan, You're right, I didn't include much information. I have CONFIG_USB_DEBUG enabled and CONFIG_USB_STORAGE_DEBUG disabled. Attached are the boot time messages for the USB hard drive. I'm using BackupPC to backup my workstation (80GB, 70% full) to the USB drive. The problem doesn't appear immediately. It may be several hours into the backup process. At one time I tried building with CONFIG_USG_STORAGE_DEBUG=y and it seemed that _every_ I/O operation got logged, which presented a problem of too much data to store. As mentioned in my post a few days ago, on the occasions I've been running overnight backups, the next morning my workstation is either hung or has rebooted. If the backup isn't running the machine is fine in the morning. FWIW, the workstation has 1G RAM and (recently) I added a 1G swap file to supplement the 1G swap partition. With the 80GB HD and its 1M files, BackupPC uses approx 1G RAM. I hope this helps explain the situation. I much like the idea of backing up to a USB HD and am willing to do what I can to help determine what's going on. Regards, David
