Hi,

After upgrading to kernel 2.6.32-431.1.2.el6.x86_64 the messages below keep appearing in "/var/log/messages".

-------------------------------------------------------------------------- ata16.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 ata16.00: irq_stat 0x40000001 scsi 16:0:0:0: [sg18] CDB: Read Capacity(10): 25 00 00 00 00 00 00 00 00 00 ata16.00: cmd a0/00:00:00:08:00/00:00:00:00:00/a0 tag 0 pio 16392 in res 00/00:00:00:00:00/00:00:00:00:00/00 Emask 0x3 (HSM violation) ata16: hard resetting link ata16: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata16.00: configured for UDMA/66 ata16: EH complete --------------------------------------------------------------------------

Output from "sginfo -i /dev/sg18" shows

Command Queueing 0 Vendor: Marvell Product: 91xx Config Revision level: 1.01

This is an unused SATA chipset on a the motherboard, no devices are plugged into it.

Also oddly I am getting

[root@mach~]# sginfo -r /dev/scanner-sg18 /dev/scanner /dev/sdb /dev/sda

"/dev/sdb" and "/dev/sda" are HD's no idea what "/dev/scanner" is?

[root@mach~]# sginfo /dev/scanner INQUIRY response (cmd: 0x12) ---------------------------- Device Type 3 Vendor: Marvell Product: 91xx Config Revision level: 1.01

-------------------------------------------------------------------------

There is no scanner attached to this machine so I am confused at the above output.
