Description t.wede 2016-01-31 19:06:57 UTC 
All drives are marked as removable, even non-removable (for example, internal SATA HDD or SSD).

cat /sys/block/sd*/removable means 1 on all physical drives (fixed or removable) instead of 0 on fixed drives

This error exists since Kernel 4.4.0. On Kernel 4.3.x it is correctly.

I can confirm this one, but is not present on all of the systems:

Created attachment 203651 [details]
small ata-removable regression patch

This patch removes a new code in the libata-scsi.c which ostensibly makes problems with some chipsets/BIOS

Disabling the hotplug functionality in the bios make the drives appears as non removable anymore; so i guess the kernel code is fine here; ti just started to support the hotplug "bit"

Just for information:

I'm also seeing this problem. In my case the bios does not have any hotplug functionality. (Gigabyte GA-MA770-DS3 with bios revision V6.00-F6)

Sorry, I'm unable to test patches.
