I run X, and the tape would read for a while and eventually the machine would simply hang and I could not change virtual consoles or do anything to find the problem. I tried reading the tape on another machine. Once it worked, two other times I had the same problem. So I tried it again, but this time I did the restore from the vt0 instead of in X. I noticed the kernel was dropping in to the debugger, with a "tag" of bt742a. What's the real problem here, and what can be done to fix it? This machine is: Copyright (c) 1992-1998 FreeBSD Inc.
