 This appears to be due to instances like the following:
 
 st0: 65536-byte tape record too big for 32768-byte user buffer
 st0(ahc0:0:6:0):  Check Condition on CDB: 0x08 00 00 80 00 00
     SENSE KEY:  No Additional Sense
                 Incorrect Length Indicator Set
    INFO FIELD:  -32768
      ASC/ASCQ:  No Additional Sense Information
 panic: kernel diagnostic assertion "delta > 0" failed: file "/l/netbsd/netbsd-4/src/sys/kern/kern_physio.c", line 441
 
 100% reproducible on head of netbsd-4 branch.
