Hey, tried to recompile kernel for a new device (VGKE B12). getting dmesg errors after compiling; not sure where to go from here:

user@user-Default-string:~$ sudo dmesg | grep silead

Any tips would be greatly appreciated.

I had a bit of luck and had noticed a minimally responsive touchscreen before the attempted upgrade, so I reverted to the default kernel, and that combined w/ the extracted firmware renamed to mssl1680.fw gives me an upper left corner output, scaled to about 1/2 vertically and 1/4 horizontally. I could probably fix it with xinput translate, but I assume I should just be able to copy the kernel entry that installs mssl1680.fw and do some quick division of the screen size to get a proper setup. The only problem is I can't find any reference to mssl1680.fw in touchscreen_dmi.c

If anyone has any ideas where to look for that, it would be great.
