We have Mips 120 Running Risc/OS 4.01 (with X25 and slip). The Machine is major networking node so we like to have it up all the time - hence we use (or rather used to use) cpio to do our backups. When we took a full backup, which usually conisted of 3 or 4 tapes the machine would crash with a !pg_ismod() problem --------- PANIC: assertion failed !pg_ismod(pt) file getpages.c, line 622 syncing disks ... (etc) ------- We now use dump to do backups and just have to put up with the downtime. We've had lots of problems with the tape drive. It seems to randomly give ioctl errors when you rewind the tape (although the tape is rewound). We've reported the problem to our local vendors so hopefully it's found it's way back to mips by now.
