I recently installed 1.6 from ISO image and it works fine except for 
scsi panic during shutdown. ( though it is not a serious problems as 
it does not destroy anything and never happens until shutdown )

Console shows :

syncing disks... 2 2 done
sd1(ihal1:0:0:0): polling command not done
panic: scsipi_execute_xs
Stopped in pid 197 (halt) cpu_Debugger+0x04: leave
db>


my system is:
Soltek-63AV+ ( VIA82C693A, though NetBSD says VIA691 )
Initio 9200UW ( dual channel )
sd0: WDE 9150
sd1: DCAS 34330 (boot)
sd2: DCAS 34330
(changing NIC,VGA makes no difference)

Is it safe to ignore this for now ?
( I did not see this when I was using 1.5-current with Initio scsi support )
