Mmm, still no replies :-)

Okay, it seems now dmesg is less verbose and no more "vpd r/w failed...". 

Now I can only see:

[    6.795461] rts_pstor: module is from the staging directory, the quality is unknown, you have been warned.

Although messages look harmless I wonder if they can be safely ignored.
