My linux kernel has an issue with Caps Lock LED on 87EC-XRGB.

I run gentoo linux on a customized linux kernel. With this kernel, Caps Lock LED on 87EC-XRGB often does not toggle when I press Caps Lock. Thus, the LED often doesn't reflect the actual status of Caps Lock. Generic kernels from binary linux distributions don't have this issue.
