I am running FreeBSD 2.0 with a Toshiba 4x CD-ROM, and I have a problem where the kernel will decide to give read errors accessing the contents of any file past some particular inode number. It is associated with the particular boot session. Removing the CD-ROM and re-inserting it (mount/unmount cycles the same) gives the same inode number. When I reboot, the number changes somewhat randomly. Sometimes I can access the whole disk, and other times, only a quarter of it. DOS and MS-Windows NT 3.5 always work fine with the CD-drive, at least I have noticed no problems, but I'll keep looking.
