 disabling dma (FDC_NODMA) recreates the RELENG_4
 behaviour :
 
 deepthought# dd if=/dev/zero of=/dev/fd0 bs=1440k count=1
 dd: /dev/fd0: Input/output error
 1+0 records in
 0+0 records out
 0 bytes transferred in 1.928038 secs (0 bytes/sec)
 deepthought# fdformat /dev/fd0
 Format 1440K floppy `/dev/fd0'? (y/n): y
 Processing fdformat: ioctl(FD_FORM): Input/output error
 
 So it's either kernel crash in isadma or broken pio,
 gotta love free choice :}
