Whenever I try to fdformat a floppy, it kill the system and the floppy
light stays on.
Someone here suggested that there could be an irq conflict.
Below is dmesg from last boot. There are no conflicts that I can see.
Any suggestions? How hard would it be to compile fdformat -g and
execute it in the debugger. I have used adb and dbx on Solaris, but
never the gnu stuff. I have all the kernel source, but do not see
fdformat.c anyplace.
