[DRBD-user] drbd module crashes at BUG at lru_cache.c:570 when the peer mode goes diskless

If drbd node in primary-primary setup looses disk by any reason (faulty
disk, controller etc., or even manual detach) and there is R/W activity
on both nodes, the second node eventually crashes with kernel panic
"kernel BUG at /root/rpmbuild/BUILD/drbd-8.4.11-1/drbd/lru_cache.c:570!"
Before the crash there are a lot of messages in kernel.log on good node
(with attached disk) like
block drbd1: al_complete_io() called on inactive extent 57
block drbd1: LOGIC BUG for enr=74
Eventually, the "good" node crashes within minutes or hours depending on
disk activity leaving the cluster without any data.
I tested different versions from 8.4 tree (8.4.6, 8.4.7-1, 8.4.9-1,
8.4.11-1), always with the same result.
There is also no difference on "real-hardware" and virtualized machines.
kernel is 2.6.32-754.12.1.el6.x86_64 on Centos-6.10 with latest updates.
Tested also on other kernels with the same outcome.
There is a vmcore-dmesg.txt attached to this email, vmcore itself is
available as well for every tested version, core files are 35-50Mb, so i
can't attach them to email, but i'll be glad to share them in some other
way if needed.

How to reproduce:
After create-md, connect, primary etc.:
On drtest-11:
pvcreate /dev/drbd1
vgcreate test /dev/drbd1
lvcreate -n t1 -L20g test
lvcreate -n t2 -L20g test
mkfs.ext4 /dev/test/t1
mount /dev/test/t1 /mnt/t1
mkdir -m 777 /mnt/t1/test
while true ; do bonnie++ -u nobody -d /mnt/t1/test/ -n 8192 -s8192 ; done
On drtest-12
vgchange -aly
mkfs.ext4 /dev/test/t2
mount /dev/test/t2 /mnt/t2
mkdir -m 777 /mnt/t2/test
while true ; do bonnie++ -u nobody -d /mnt/t2/test/ -n 8192 -s8192 ; done
drbdadm detach r1
After the detach on drtest-12, drtest-11 almost instantly starts
flooding the log with " al_complete_io() called on inactive extent" and
"LOGIC BUG for enr=" and crashes within couple of minutes.
Thanks in advance for investigating this issue.
