Hello kernel people,
the attached oops happens when I try to create an md-array on an aoe device
in conjunction with vanilla Kernel 2.6.15+drbd+aoe:

--cut--
Oops happens while the following ioctl is running:
ioctl(3, 0x40140921 <unfinished ...>
fd3 is /dev/md0
The command I have been using was:
mdadm -C --level=raid1 -n 2 --auto=md /dev/md0 /dev/etherd/e1.0 /dev/etherd/e2.0
Concerning the strace Output I would assume a bug in the md code rather
than aoe. Unfortunaltely I am unable to test this with generic IDE devices.
Regards
Sven
