Running FC2 I upgraded my system with yum that replaced the kernel 2.6.5 with 2.6.6.1. >From that time usb devices (printer, memory stick) no longer work. In order to use these, i must boot with the old kernel. At boot, the new kernel displays a message saying that my printer has been deleted. After that if I try using a usb-key, I get the message "/dev/sda1 is not a valid block device". At no time, the usb key seems to be active (red lights never lit). etc/fstab looks like /dev/sda1 /mnt/removable auto noauto,user,sync 0 0 What's wrong. Thanks for help. -- fedora-legacy-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-legacy-list
