+## Can't read column of matrix beyond 16 \r
+Use `1UL<<16` instead of `1<<16` in `read_cols()` in **matrix.h** when your columns goes beyond 16.\r
\r
In C `1` means one of **int** type which is **16bit** in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say `1<<16`. You have to use **unsigned long** type with `1UL`.\r

+## Problem on BIOS(UEFI)/Resume(Sleep&Wake)/Power cycles\r
+Some people reported their keyboard stops working on BIOS and/or after resume(power cycles).\r
+\r
+As of now root of its cause is not clear but some build options seem to be related. In Makefile try to disable those options like `CONSOLE_ENABLE`, `NKRO_ENABLE`, `SLEEP_LED_ENABLE` and/or others. \r
