Running last Friday's sources I have a big problem on a Sun3/80. Configuration is

| esp0 at obio0 addr 0x66000000 ipl 2: ESP100, 20MHz, SCSI ID 7
| scsibus0 at esp0: 8 targets
| sd0 at scsibus0 targ 0 lun 0: <MICROP, 1588-15MBSUN0669, SN0C> SCSI1 0/direct fixed
| sd0: 639MB, 1632 cyl, 15 head, 53 sec, 512 bytes/sec x 1309735 sectors
| st0 at scsibus0 targ 4 lun 0: <EXABYTE, EXB-8200, 425A> SCSI1 1/sequential removable
| st0: density code 0x0, 1024-byte blocks, write-enabled

Everything works fine until I use the tape drive. I write a 1024 byte record and if
I read it back, all data is shifted up by 4 bytes. As a side effect parts of the
file system on sd0 get corrupted.
I don't know if the sources before last Friday had the same problem.

Any ideas anyone?
