After recompiling, rebooting and run afdbench first I got an OOPS and the
system hanged up solid. The only thing I was able to catch is this:

RIP [<ffffffff803019f9>] jbd2_journal_release_jbd_inode+0xcb/0x100
RSP <ffff8101fe259c18>

This was copied by hand. And this I cut 'cut and past' from my terminal:

kernel: Code: c3 e8 31 ce f3 ff 41 fe 04 24 e8 fe 3f 16 00 4c 89 fe 48 89 df e8 5f cd f3 ff eb 82 48 83 7d 00 00 74 27 48 8b 55 10 48 8b 45 18 <48> 89 42 08 48 89 10 48 c7 45 18 00 02 20 00 48 c7 45 10 00 01

So I rebooted run bonnie and then afdbench and I get the same problem as
yesterday. All process trying to write something to this filesystem hang
in D-state. But now I was able to do the echo t > /proc/sysrq-trigger.
Here the dmesg output:
