"/sys/block/sd(X)/removable" erroneously indicates "removable" for fixed drives

[b3nmore]

This seems to happen only to additional hdd (not the one with the root partition). gnome-disks and some file manager report those drives as ejectable.

This might be fixed by the following patch http://git.kernel.org/cgit/linux/kernel/git/stable/stable-queue.git/diff/queue-4.4/ata-ahci-don-t-mark-hotplugcapable-ports-as-external-removable.patch?id=4e362751dc079531ef2b95bcd5c71e12f78e1ae6

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Tested with latest mainline v4.6-rc4-wily, issue still persists.

[b3nmore (b3nmore)]

According to a redhat bug report (https://bugzilla.redhat.com/show_bug.cgi?id=1310682) it was introduced by a kernel update from 4.3 to 4.4. So I've testet 4.3.6 from mainline and it is not effected.

Btw. you probably get this on a live system too and for all hdds (since root is on the flash drive). This can have quite an impact, because some DEs automatically mount all removable drives (e.g. kde). If one of your hdd partitions contains a hypernated system, your in for a lot of fscking and/or ro mounted partitions on next resume.
