Hi Tejun, Hans,
The SAMSUNG SSD PM830 factory-installed in my Dell XPS 13 (Ivy Bridge)
works fine with older kernels, but exhibits ata errors in recent

Could you please review & apply the attached patch (git format-patch)?
In short:
+ { "SAMSUNG SSD PM830 mSATA 256GB", "CXM13D1Q", ATA_HORKAGE_NOLPM, },
This is the second report of the msata version of the 830 (both are PM830 drives)
having issues with LPM, at least for the "CXM13D1Q" and the "CXM14M1Q" firmware versions.
Can you change your patch to replace the 256GB part with a "*" I believe
all capacities will be broken and then officially submit this upstream with
my:

Added please?
Thanks & Regards,
