Bug 139187

Description of problem:

somewhere after kernel-2.6.6 my external USB dvd-writer stopped being
recognized properly...it came up as "revoltec" and so i lingered at
2.6.6 waiting for the glitch to pass.  with fc3, i got a new kernel
and tested the USB disk enclosure by plugging it in and watching the
log...satisfied that it was recognizing the drive instead of the
usb-ide-bridge "revoltec?", i unplugged it and that's when i got the
crash...

Summary     : The Linux kernel (the core of the Linux operating system).
Description :
The kernel package contains the Linux kernel (vmlinuz), the core of
the Red Hat Linux operating system. The kernel handles the basic
functions of the operating system: memory allocation, process
allocation, device input and output, etc.


How reproducible:

plug in semi-generic usb/ide box (some aspects of usb-storage called
it 'revoltec' in recent kernel versions)...then unplug it...BOOM
