Hi Sir,


We have a product which uses Intel Xeon Processor E3 v5 CPU, we found an is=
sue
of I915 graphic driver. The testing OS is CentOS7 with kernel 3.10.0-514.10=
.2 &
the OS only has the text mode, after boot up we plug-out the VGA cable and =
then
plug-in the VGA cable again, then the VGA screen shows no signal. On the sa=
me
OS we remove the I915 module from initramfs & do the same plug-out &=
; plug-in
test again, the VGA screen can still got the signal back.

We also do the same test on WIN10 PRO X64, it doesn=E2=80=99t have the VGA =
no signal
issue. It seems the root cause is the I915 driver, could you assist to chec=
k it
or do you have newest I915 driver source code for us to do the test? Thank =
you!
