<pre>Hi Sir,
We have a product which uses Intel Xeon Processor E3 v5 CPU, we found an issue
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 same
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’t have the VGA no signal
issue. It seems the root cause is the I915 driver, could you assist to check it
or do you have newest I915 driver source code for us to do the test? Thank you!
