It's not clear what you are doing. Do you mean:
menuentry "Linux 4.11.0-lfs-20170507-nvidia /dev/sda16" {
linux /vmlinuz-4.11.0-lfs-20170507-nvidia root=/dev/sda16 ro
}
and edit the linux line? If so, what is the before and after?
You need to be more specific so we can help you.
Apologies. Yes, very much like that. This 7.7 host appends
"video=640x480-16 nomodeset" to the line. I was trying to stay
close to the pattern that worked. As I was trying to debug my
X/startx failure (see blfs-support list), it was suggested I
remove the nomodeset bit. When I backspace-deleted it I got
reliable kernel panics using two different GRUB hosts on this
box. If I didn't delete that last parameter I didn't. It
booted without error--other than X still failed. ;-) With the
"nomodeset" it does work fine on this 7.7 system on the same
box, and did from the start.
Doing the same backspace-delete on this 7.7 host doesn't kernel
panic. I've since rebuilt the offending kernel with as much
careful attention as I know to getting the options as they should
be--using a diff with this 7.7/3.19.8 host as a guide to the
Graphics options--and it hasn't panicked yet. I'm uneasy "letting
it go", but for now I am and going back to the X problem. I have
a post to make on the blfs mailing list.
IIRC I think that nomodeset will not allow xorg to start.
I can't address the kernel panic explicitly, but as a debugging technique,
try building a vanilla kernel with 'make defconfig' and see if that works.
Trying a different kernel is relatively quick and you only need a short
entry in grub.cfg. Alternatively, you can skip modifying grub.cfg
completely and just hit e at the appropriate entry at boot and edit the
name of the kernel to use.
I generally differentiate my kernel names with an entry in
General setup -> Local version
-> Automatically append version info to the version string
That allows a different set of modules when you run 'make modules_install'
