Bug#813876: [linux-image-armmp] Unable to handle kernel NULL pointer dereference
Package: linux-image-armmp
Version: 4.3.0-1
Severity: important
I try to boot my Wandboard Quad with
http://ftp.uk.debian.org/debian/dists/stretch/main/installer-armhf/current/images/netboot/SD-card-images/firmware.Wandboard.img.gz
+ partition.img.gz
If no HDMI monitor is connected the kernel stops with an error:
[ 2.852064] imx-drm display-subsystem: failed to bind 120000.hdmi
(ops dw_hdmi_imx_platform_driver_exit [dw_hdmi_imx]): -517
[ 2.877979] Unable to handle kernel NULL pointer dereference at
virtual address 00000004
Starting system log daemon: [ 2.886157] pgd = c0004000
If a monitor is connected the failure does not occur. But since I want
to run the Wandboard without monitor this is no solution.
Best regards
Heinrich Schuchardt
