[vox-tech] what is a bus error

[Rod Roark]

Drivers don't access buses directly, but rather by reading from 
and writing to I/O or memory addresses, or by fielding interrupts.
So I think any "bus error" message is going to be hardware-specific.

However a "buss error" would pertain to "software".  ;-)
