>Environment:
 Pentium II machine, 128M of memory, tested with a customised
 kernel, and with a standard kernel.
>Description:
 When ide cdrom (panasonic 24x) and ide zip drive (iomega) are on same
 ide bus, accessing the cdrom hangs the system completely. It is not
 possible to cleanly stop the system in this state. The zip drive appears
 to work OK. Both drives work fine under win-95 and win-nt. Both drives
 are correctly detected and identified during boot, including identifying
 that media is loaded in cdrom drive.
>How-To-Repeat:
 Problem is consistent, fails all the time when cdrom and zip drive are both
 present in the system.
>Fix:
 No known workaround.
