commit 1066fe825987da007669d7c25306b4dbb50bd7dd upstream.
We got another report that CT1000BX500SSD1 does not work with LPM.
If you look in libata-core.c, we have six different Crucial devices that are marked with ATA_HORKAGE_NOLPM. This model would have been the seventh. (This quirk is used on Crucial models starting with both CT* and Crucial_CT*)
It is obvious that this vendor does not have a great history of supporting LPM properly, therefore, add the ATA_HORKAGE_NOLPM quirk for all Crucial BX SSD1 models.
