I just installed 5.3 on a tower box. When I plug in a usb flash drive, the machine crashes. I don't know how to diagnose the problem; I used gnome-system-log, and got this (watching it as I plugged it in): Apr 12 16:43:25 ga7zx kernel: usb 1-2: new full speed USB device using uhci_hcd and address 2 Apr 12 16:43:25 ga7zx kernel: usb 1-2: configuration #1 chosen from 1 choice Apr 12 16:43:27 ga7zx kernel: Initializing USB Mass Storage driver... As this point, the whole system becomes an ice cube - I can't even 3-finger salute to reboot. This happened a few times - same result. The board is a Gigabyte with an AMD Athlon 1.3 GHz cpu. Be aware that this drive works fine on 3 other boxes (with 5.3, Fedora 7, and Fedora 8). What could be wrong? What else should I check? How do I fix it?
