Well, duh ... tapes are fun. Wonder why no one seems interested in them 
nowadays.

OK, I'll see if I can reproduce this on 2.4.20. 

It would be nice to get a newer kernel to work in real use too... funny 
that KDE should lock up though, that's not a symptom that I'd expect to 
see.

Well, 1010d4e8 seems to be in the middle of something...
1010d1c0 t pcxl_proc_info 	
1010d30c t .L1066
1010d36c T inb
............. lots of other "t .L???"s and an occasional "T inw"
1010d480 t .L708
1010d484 T inl
1010d4ec t .L712

1024a2d0 seems much more readable here... but then again the stuff is 
much further apart.

1024a2ac t dino_in32
1024a2e4 t dino_out8
1024a320 t dino_out16

Indeed, and on HP-UX I've seen occasional HPMCs with slightly-broken 
disks, for example...
