After upgrading to Ubuntu 14.10 I can see these worrying lines, printed
in red, from my `dmesg` output:

[ 3.192349] ata14.00: exception Emask 0x1 SAct 0x0 SErr 0x0 action 0x6 <-- printed in red
[ 3.192395] ata14.00: irq_stat 0x40000001 <-- printed in red

[ 3.520821] ata14: EH complete

Any ideas where the exception and HSM violation is coming from?

The next section with a similar issue is:

[   14.172661] ata8.00: exception Emask 0x1 SAct 0x0 SErr 0x0 action 0x0 <-- printed in red
[   14.172712] ata8.00: irq_stat 0x40000001 <-- printed in red

[   14.172879] ata8.00: status: { DRDY ERR }
[   14.172922] ata8.00: error: { ABRT }

Been searching everywhere for solutions but found no working one. Any
clues? Any answers very welcome.

Thanks!!
