What is this ata exception



Hi,

I saw the following for the first time when I rebooted just now:

Mar 31 09:10:04 cxmr kernel: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
Mar 31 09:10:04 cxmr kernel: ata1.00: cmd b0/d2:f1:00:4f:c2/00:00:00:00:00/00 tag 0 cdb 0x0 data 123392 in
Mar 31 09:10:04 cxmr kernel: res 50/00:f1:00:4f:c2/00:00:00:00:00/00 Emask 0x202 (HSM violation)

Mar 31 09:10:04 cxmr kernel: res 50/00:f1:00:4f:c2/00:00:00:00:00/00 Emask 0x202 (HSM violation)

Mar 31 09:10:04 cxmr kernel: ata1.00: configured for UDMA/133
Mar 31 09:10:04 cxmr kernel: ata1: EH complete

It repeated several times after. What does it mean?

FYI, my box experiences sudden freeze and lock up recently so I enabled my
smart monitor. In fact the reason for the reboot is that the system locked
up entirely. It all goes like this, I didn't do anything, and it freezes.

BTW, I am still not quite sure what will happen when I enabled smartd. Do
I get report from cron, or I have to pull it myself from time to time?

Thanks
