Here, I think I captured the panic correctly, ksymoops must be reliable this time. This report is an extension to the thread named "blacklist a device in usb-storage" at: http://marc.theaimsgroup.com/?l=linux-kernel&m=109250806001443&w=2 The dmesg output until the panic are in dmesg2427v.out. The painc info went through ksymoops is in panic-27.out. Ozkan Sezer
