Subject: 2.6.15: oops in sysfs_create_link
Date: Fri, 13 Jan 2006 17:30:43 +0100	[thread overview]
Message-ID: <20060113163043.GA5417@geggus.net> (raw)

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:

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
