in 4.1.10 my USB connected harddrive gets fully powered down from time to time, only a reset of the raspberry helps. Due to being there my OS my raspberry freezes complete. Interestingly only the HDD connected via "JM20329 SATA Bridge" is powered down. A "Western Digital Technologies, Inc. Elements 2TB" does not show this issue as far as I can see.

Are you reporting this as a bug or just a comment?
I think if you power off the harddrive that contains the OS then you are in undefined behaviour territory and I doubt we can do anything to fix that.

The bug, if indeed that is what it is, is that the powering down is spontaneous and unrequested.

What happens is, that the drive powers down by usb-command which is not issued by any application. And it only happens in newer kernels. I tried 4.1.9 and 4.1.10 which both failed, whereas 4.1.6 is definitely stable. (all via rpi-update ). If it is wanted I could try 4.1.7 and 4.1.8 also.

What do you mean by "powers down"?
You can't power the drive down from a usb command. Are you talking about a "spin down"?
Can you post a dmesg log after the failure.
Can you describe how the drive is connected and powered? Sounds more like an inadequate power supply for the drive.

Hardrive gets resetted, and put into sleep mode. LED is off, as opposed to normal mode where it is lit, and on access blinking. (Same as if I unmount it via Windows)
I cannot get a dmesg log, as OS cannot load anything, due to harddrive being down.
Drive is directly connected to raspberry, and powered by original power-supply. (And is running since 13111 hours without any troubles). Harddrive is running on 4.1.6 now since 57 hours without troubles. In 4.1.10 problem occured after 30 minutes to 2 hours.

If you could identify the exact firmware update (and so which 4.1.x kernel version) that introduced the issue, we could have a look through the commits and see if anything stands out.

Closing USB issues as OP has not updated the thread. Further comments by the OP stating that the issue is still present on latest rpi-update kernel will lead to a review.
