growisofs 7.1: problem past first layer on BD-R DL

Hi all,

having been successfully using growisofs for many years with
varying DVD SL/DL and BD-R SL media, I've been unpleasantly
stung today, trying to write BD-R DL for the first time.

Software versions:

    $ uname -a
    Linux hostname 2.6.39-bpo.2-amd64 #1 SMP Thu Aug 4 11:42:06 UTC 2011 x86_64 GNU/Linux

    $ cat /etc/debian_version 
    6.0.5

    $ growisofs -version
    * growisofs by <[email protected]>, version 7.1,
      front-ending to genisoimage: genisoimage 1.1.11 (Linux)

Command line (used to successfully burn very many a BD-R SL on
the same machine, varying -speed accordingly):

    $ growisofs -use-the-force-luke=spare:none -speed=4 \
	-Z /dev/br <genisoimage-options-here...>

The media is VERBAT/IMf, BD-R DL 1--6x by Mitsubishi Kagaku
Media Co, purchased in Tokyo.  The first failure was at 6x
speed, the second at 4x.  Both times, it ended like so, at the
same LBA=ba7410h offset:

     50.04% done, estimate finish Mon Sep 10 00:43:45 2012
     50.06% done, estimate finish Mon Sep 10 00:43:46 2012
     50.09% done, estimate finish Mon Sep 10 00:43:45 2012
    :-[ WRITE@LBA=ba7410h failed with SK=5h/INVALID ADDRESS FOR WRITE]: Invalid argument
    :-( write failed: Invalid argument
    /dev/br: flushing cache
    /dev/br: closing track
    /dev/br: closing session
    /dev/br: reloading tray

Here's the media info _after_ the failure (also shows the
hardware and firmware being used):

    READ CAPACITY:          12219408*2048=25025347584

The error happens after exactly half the capacity plus one
single 32 KiB block.  The stop point, in 2 KiB block terms:

    0xba7410 == 12219408 == 24438784 / 2 + 16

After the failure, the recorded 12219408 blocks of 2 KiB read
back in completely fine.  The final blocks of the session
contain garbage.  It's also possible to then write more sessions
to the remainder of the disk (via -use-the-force-luke=seek:xyz)
successfully.

It seems there may be a problem when just starting to write the
second layer.

Before I continue to experiment with the costly BD-R DL blanks
(I haven't any BD-RE DL, so the next thing is to try cdrskin, I
suppose, or removing -use-the-force-luke=spare:none), can anyone
please share similar or contrary experience with the same or
similar software, hardware and/or media?  Any clues to the
reason or any other hints?

(Please refrain from suggesting to check various cabling, hard
disk speed issues, automount interference and other non-specific
things.  A few BD-R SL, including VERBAT/IMe from the same
series by MKM, were recorded before and after these problems on
the same rig, zero issues.)

Cheers,
