asyn_notify(n), smart(y), fua(y), sw_preserve(y) I don't see a clear pattern yet, but I suspect warm rebooting >=4.2 after having run 4.1.x leads to sucessful driver inits. But I also remember having had cold boots, with kernels >=4.2 that worked fine (obviously not all of the time). <=4.1.20 kernels on the other hand boot fine every single time. Interestingly the igb driver (ethernet) seems to be acting up at least with 4.5.0 on exactly the same boots when mpt2sas init fails. I don't know whether this could be connected or not (I just became aware of this coincidence). --- Matthias Am 21.03.2016 um 05:53 schrieb Sreekanth Reddy: > Hi Matthias, > > Can you please share us the driver logs with driver logging_level set > to 0x3f8.
