Hi Shaohua,
It seems this patch fixed my issue ! Had the issue remaining in 4.13.3,
after patched with the following patch, issue seems to be gone. I can't
reproduce it anymore.
Thanks anyway ;)

Hi guys,
Finally the problem is still present, but harder to reproduce, I
couldn't reproduce it with fio... But syncing DRBD stack finally made
the kernel crash again :
May 13 05:33:49 Node_2 kernel: [ 7040.167706] [ cut here
]

Hi Shaohua,
I've made some new little tests, maybe it can help.
- I tried creating the RAID 5 stack with only 2 drives (mdadm --create
/dev/md10 --raid-devices=3 --level=5 /dev/sdc1 /dev/sdd1 missing).
The same issue is happening.
- but one time (still with 2/3 drives), I was not able to crash

Hi Shaohua,
Thanks for your reply.
Let me explain my "huge". For example, if I'm making a low rate i/o
stream, I don't get a crash (<1MB written / sec) with random i/o, but if
I'm making a random I/O of about 20MB/sec, the kernel crashes in a few
minutes (for example, making an rsync, or even

Hello,
Thanks for your reply. DRBD isn't part of the kernel ? I was thinking it
has been included since 2.6.3x ?
I've just tested without DRBD, the issue seems to remain. Can't see the
"BUG", but the kernel crashed also. (A little bit later)
I don't have full dump since I lost my network conn

Hi guys,
I've tested the same set-up except with a RAID 1 Soft Array, in this
case I get no issue at all.
It's definitely a raid 5 problem.
As requested, I've tested re-creating the RAID 5 array (just to be
sure), issue remains the same, even with metadata 0.90 or metadata 1.2.
Thanks,

Hello Guys,
I've having some trouble on a new system I'm setting up. I'm getting a kernel
BUG message, seems to be related with the use of Xen (when I boot the system
_without_ Xen, I don't get any crash).
Here is configuration :
- 3x Hard Drives running on RAID 5 Software raid created by mdadm
