Hi,
I recently set up a box with (basically) 2.6.32.2 (specifically
gentoo-2.6.32-r1), and got the warning below when I started up smartd,
which is set to scan all the devices. This machine has an Areca
1300ix-16 controller (mvsas driver, no raid), and a number of WDC
WD20EADS-00S2B0 drives attached (2TB, SATA).
That would appear to be this:
if (ata_is_ncq(prot)) {
..
} else {
WARN_ON_ONCE(link->sactive);
which means that something (presumably smartd) was issuing a non-NCQ
command while NCQ commands were active, which shouldn't be allowed. Some
issue with the NCQ defer behavior with mvsas?
Please let me know if you need any other information.
