The patch below should fix that, thanks for the bug report.
fdioctl() historically attempted to determine the "raw" partition
(`c') of the device in order to read the label. However, the floppy
driver never really supported UFS-style partitions anyway. This ended
up in selecting the wrong device for reading the label, which was a
not-so-fatal error before the last floppy driver rewrite (it actually
selected the fdX.1480 device then, which was obviously benign for 3.5"
drives). However, now it hits an unitialized device which becomes
fatal in readdisklabel() by attempting an indirect call to the
strategy routine that hasn't been entered in the struct dev passed
The call to dkmodpart() entered in rev. 1.64 of fd.c, so i'm Cc'ing
Bruce for a comment whether the fix below is indeed TRT.
