Description of problem: System configuration: CPU : NOCONA 3.6G stepping E-0 (D-0 also happen) Memory : 512MB HDD : SCSI 18G North bridge : E7520(Lindenhurst) South bridge : ICH 5 (Hance Rapids also happen) I get the message "usb-uhci.c: c interrupt, status 3" followed by various frame numbers on all tty terminals when I plug in two USB devices(floppy and CD-ROM). Version-Release number of selected component (if applicable): kernel 2.4.21-4.ELsmp How reproducible: Steps to Reproduce: 1. Plug in two USB devices(floppy and CD-ROM) and don't put any disk into devices. 2. Turn on the system power. 3. Boot to Linux ES release 3. 4. Login X-windows. 5.Toggle to a tty (cntl-alt-f1, etc) 6. Wait about 5 seconds and you will see the following messages.

results: I see the "usb-uhci.c: c interrupt, status 3" message.
