Both work fine most of the time, but every so often on change of CD media the ATAPI driver wedges solid, and the only apparent solution is a reboot. I had this problem about 6 months ago (and saw from the archives that it's a problem), and disabled the ZIP as I didn't really need it at that stage. It doesn't occur as frequently now as it used to (I'm running 2.2-STABLE cvsupped one week ago). Is there any way of unwedging the ATAPI driver without rebooting? Would using the atapi LKM and doing a modunload/modload help, or cause Bad Things to happen?
