I'm trying to install 1.6beta2 snapshot on two SS1+ machines.  Install
was OK on a Fujitsu SCSI disk and I copied the disk to a Seagate using
dd, hoping to speed things up.

The system boots with the Fujitsu, but not with the Seagate (which was
working OK under NetBSD 1.3.3).  With Seagate, kernel is loaded, but
the boot freezes a bit later:

....
scsibus0 at esp0: 8 targets, 8 luns per target    
le0 at sbus0 slot 0 offset 0xc00000 level 5: address 08:00:20:08:ad:1a
le0: 8 receive buffers, 2 transmit buffers        
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 2 lun 0: <SEAGATE, ST31230N, 0300> SCSI2 0/direct fixed
sd0: 1010 MB, 3992 cyl, 5 head, 103 sec, 512 bytes/sect x 2069860 sectors
sd0: async, 8-bit transfers, tagged queueing
Kernelized RAIDframe activated
root on sd0a dumps on sd0b
root file system type: ffs
esp0: identify failed, state 3, intr 0c
<dropping msg byte 0>esp0: unexpected disconnect; sending REQUEST SENSE
<dropping msg byte 0><dropping msg byte c0>esp0: unexpected disconnect;
sending 
REQUEST SENSE
esp0: target didn't send tag: 0 bytes in fifo

I can ctrl-c and get to sh, but if I type exit, the system does not boot
up.

I'm also seeing SCSI messages in syslog:

(esp0:0:0): select; 1 left in DMA buffer [intr 18, stat 10, step 4]
Jul 26 12:00:04 reipas /netbsd: (esp0:0:0): select; 1 left in DMA buffer
[intr 18, stat 10, step 4]
(esp0:0:0): select; 1 left in DMA buffer [intr 18, stat 10, step 4]
Jul 26 12:00:46 reipas /netbsd: (esp0:0:0): select; 1 left in DMA buffer
[intr 18, stat 10, step 4]

Are these messages fatal?

I'll try building a kernel soon, but I'm not sure if the build completes
before Christmas (have these machines always been this slow!? ;-)
