SparcClassic (sun4m, Sun 4/15) running the GENERIC kernel from the
2.0.2 distribution (see the startup messages in the full description)
>Description:
Formatting a floppy using the built-in 3.5" floppy drive reliably crashes a SparcClassic; most likely there is no hardware problem involved, since formatting the same floppy disk on the same hardware works under Solaris (Solaris 2.5.1 and Solaris 7) and OpenBSD (3.7, generic kernel).

Logs of both the startup messages and the crash messages follow.
