>Description:
Since I changed the motherboard of my server recently it doesn't
detect the SCSI DVD-ROM properly anymore on system startup:

siop0 at pci3 dev 12 function 0: Symbios Logic 53c810a (fast scsi)
siop0: interrupting at ioapic0 pin 20 (irq 10)
scsibus2 at siop0: 8 targets, 8 luns per target
siop0: unhandled scsi interrupt, sist=0x400 sstat1=0x8 DSA=0x309d000 DSP=0x28
siop0: unhandled scsi interrupt, sist=0x400 sstat1=0x8 DSA=0x309d14c DSP=0x28
siop0: scsi bus reset
probe(siop0:0:2:0): command with tag id 0 reset

The SCSI tape drive however is detected:

st0 at scsibus2 target 4 lun 0: <SONY, SDT-9000, 0400> tape removable
st0: drive empty
st0: sync (100.00ns offset 8), 8-bit (10.000MB/s) transfers

If I use "scsictl scsibus2 scan all all" after the system is up it finds
the DVD-ROM ...

cd0 at scsibus2 target 2 lun 0: <PIONEER, DVD-ROM DVD-303, 1.09> cdrom removable
cd0: sync (100.00ns offset 8), 8-bit (10.000MB/s) transfers

... and I can use it without problems.

>How-To-Repeat:
In my case: booting my system.
