https://bugzilla.kernel.org/show_bug.cgi?id=63981 --- Comment #4 from Theodore Tso <tytso@xxxxxxx> --- BTW, I'm using a 512GB Samsung 840 PRO (2.5" SATA SSD) and an 240GB Intel 525 SSD (mSata) on my Lenovo T430s, and they both work like a charm. Hmm... I wasn't able to get detailed specs on your SAMSUNG MZNTD256HAGL-00000, but upon doing some further research, it appears to be a new-fangled M.2 PCIe interface. So it's not a mSATA nor a 2.5" SATA interface, but Something New. So whether or not this is a Linux bug, or an implementation bug in this new Samsung part (or a failure in the standardization of this new M.2 PCIe interface), I can't say, but this looks like the most likely cause is a problem with this new SSD or its new M.2 interface[1].
