Hello, after last cvsup and make world (around Oct 10 5:00 GMT) on shutdown it now reports: syncing disk ... 3 3 done. (da1:ahc0:0:1:0): SYNCHRONISE CACHE. CDB: 35 0 0 0 0 0 0 0 0 0 (da1:ahc0:0:1:0): ILLEGAL REQUEST asc:20,0 (da1:ahc0:0:1:0): Invalid command operation code sks:c0,0 So booting -v --------------------------------------------------------------------------- ahc0: target 0 synchronous at 10.0MHz, offset = 0xf ahc0: target 2 synchronous at 10.0MHz, offset = 0xf (probe6:ahc0:0:6:0): INQUIRY.

All the disk scsi params are at the default settings. As I read it from the Seagate Medalist Pro 2160N Product Manual, Rev B the CDB (command Descriptor Block) is 12 Inquiry Command 1 Enable Vital Product Data (1 means enabled) 80 The page of the vital product information (since EVPD is set) 0 page code continued ff Allocation length in bytes 0 a CDB must end in zero According to the manual this looks like a valid CDB but ... it reports Illegal Request error code 24,0 which is "The drive received a CDB that contains an invalid bit" And how do you interpret "invalid field c8,1"? This probably explains why the disk doesn't do tagged queuing. System is working ok, but if I could get rid of the message and get tagged queuing it would be nice.
