I'll test the following patch the next days to disable NCQ. Adding a kernel
param to disable ncq would also be great:

Created attachment 248991 [details]
Tested patch with correct string to identify the disk.
Here a new patch as attachment with the real patch. Seems to work fine
here. Even better (optimum?) would be a change where a param can specify the
queue depth, with 0 disabling NCQ.
Let me know if this should also get submitted upstream somewhere to get
this into the upstream kernel.
regards and thanks for the beautiful kernel,
Florian La Roche
Closing this, probably fixed by other patches already. regards, Florian La Roche
I am not clear exactly what is the root cause of the issue here.
What are some of the symptoms besides seeing these error messages in the dmesg or /var/log/messages?
In my case, I am running this version of the RedHat.

Is this an hardware issue?
This is the drive that I am using:
