die Meldung kommt aus dem Queue full event handling code des mpt Treibers, die Kommentare des Entwicklers dazu lassen weiterhin einen Hardware-Problem vermuten:
MPTSAS driver has support for QUEUE FULL event introduced in 2.6.31.
These prints are related to QUEUE FULL events messages.
If you remove below patch things may work fine for you.
git.kernel.org/cgit/linux/kernel ... 55d225677e
Now coming to the real issue.
I am suspecting there may be IO errors with your drive coming very frequently.
QUEUE FULL event is coming from Firmware whenever any change happens in device queue depth. This will only
happens in IO error path. (We can think of flow control will kicked off when IO error occurs at firmware
level and they will inform Driver saying Queue full event).
In other words,
If you replace with newer SAS drive, things may work fine even with 2.6.31.
As you have mentioned that this SAS drive was previously used for striping, there may be possibility of poor
performance of your SAS drive.[/quote]
