>Description:
After upgrading from NetBSD 1.6W to 1.6ZC my SPARCStation LX produces the
following message on system startup:

dma0 at sbus0 slot 4 offset 0x8400000: DMA rev 2
esp0 at dma0 slot 4 offset 0x8800000 level 4: ESP200, 40MHz, SCSI ID 7
scsibus0 at esp0: 8 targets, 8 luns per target
[...]
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 0 lun 0: <IBM, DCAS-34330, S65A> disk fixed
sd0: fabricating a geometry
sd0: 4134 MB, 4134 cyl, 64 head, 32 sec, 512 bytes/sect x 8467200 sectors
sd0: sync (100.00ns offset 15), 8-bit (10.000MB/s) transfers, tagged queueing
root on sd0a dumps on sd0b
sd0: fabricating a geometry
sd0: fabricating a geometry

It looks very suspicious to me that sd(4) isn't able to get the geometry
from that disk and has to fabricate one.

>How-To-Repeat:
Boot system and watch kernel messages.

None provide.
