Hello First off, I would like to clarify that I was redirected here from gentoo-user (see my thread at http://archives.gentoo.org/gentoo-user/message/5677e2044aba73c5ac046a2a634f801a). If this is the wrong list for issues like this, please direct me to the proper place. Also, while I searched the net beforehand, the "best" I could find were Ubuntu forum entries ([0] and [1], both sans resolution), so please excuse me if this has already been reported.
Now, the problem I'm facing is that the logical sector size on my external HDD
is being incorrectly detected on initial connect. The symptom that follows
from this is that the none of the partitions can be mounted. I get the
following dmesg entries:

(I picked these out of the entire dmesg (well, "journalctl -k") output, so
I hope nothing important is missing.)
I have to unplug it and plug it back in, after which it works correctly (as can
be seen in the log above). It appears to be important that my PC has been cold
booted, as that is the only time when I can reliably reproduce this. The
precise scenarios I have tested that *work* are:
- turning off the HDD (i.e., unplugging the AC) while leaving the PC on, then
turning it back on several hours later, and
- rebooting my PC (while the HDD stays on).
I also tried it on my brother's Windows 8 PC, where the drive was correctly
detected and the FAT32 test partition was mounted (once Windows installed
drivers and whatnot; I did *not* install drivers manually). The above problem
did not show up after moving it back to my PC immediately afterwards.
Also, the drive originally had an MBR, but in the meantime I converted it to
GPT (using cgdisk), since the firmware "translation" mentioned in [0] and [1]
is supposedly there to keep MBR working, but it did not change anything.
Finally, I also tried blacklisting the uas module, but again, no change.
If I'm unlucky, it's a firmware problem, but I hope that it's something that can
be fixed in the relevant driver.

The above information is from when I was running Linux 3.18.9-gentoo, but I've
also tested with 3.19.2-gentoo and upstream 3.19.2. I'm not sure whether I'm
prepared to test an RC kernel, but I suppose I could be persuaded.
