Just wondering if there's an unforeseen problem with PDS cards in 
Macintosh LC 68040-based machines, because before I added the ethernet 
card, this machine would boot beautifully, and I could run vi, ex, or any 
other text editor I wanted to. 

Now I am having troubles getting just about any text editor to work on my 
Mac. What happens is, if I start vi or ex or ed, I will get a core dump 
either after I make my edits or if I try to refresh the screen. This will 
happen when I try to save a pre-existing file or a new file. After I get 
the core dump, I am unable to get an ls of the directory the core dump 
happened in.  And even after changing to another directory, and then 
changing back to the original directory, ls still reports no files, not 
even . or .. But if I use the shell redirection, I can successfully 
create new files.  I just can't use an editor to display or edit them and 
expect to be able to save the result.

On boot, I get the message that kvm_mkdb: /var/db/kvm.db.tmp: 
Inappropriate file type or format.

If I manually try to run kvm_mkdb in single-user mode, I get the same 
message. 

My machine is an LC 475, that boots with a serial console.  It has an 
FPU, 36 MB RAM, the root drive is a Quantum ELS80, 83 MB hard disk, 
formatted with A/UX's HD SC setup. The usr filesystem is an Apple-labeled 
Quantum LPS270S, also formatted with A/UX HD SC Setup. The machine has 67 
MB swap on the root filesystem, a 16 MB root filesystem, and a 260 MB usr 
filesystem. The machine  has an Asante MacConi-LC ethernet card in its 
PDS slot, that is recognized (its MAC address gets printed out).

I have installed the April 7th snapshot of NetBSD on the hard disks of 
this machine. 

I have tried this machine with John Wittkoski's HWDIRECT #164, and the 
GENERICSBC #16, 25, 26, 27, and 28 kernels, all with the same result. 

Thanks in advance for any suggestions or information,
Steven
