+Kernel Configuration
+^^^^^^^^^^^^^^^^^^^^
+If you build a custom kernel, note the following configuration items:
+
+- CONFIG_CRC_CCITT must be enabled ('y' or 'm'). On 2.6 kernels this can
+  be selected These can be selected from the "Library Routines" submenu
+  during kernel configuration via "make menuconfig".
+- DAHDI will work if you disable module unloading. But you may need
+  extra reboots.
+- DAHDI needs the BKL (Big Kernel Lock). This may be annoying in
+  >=2.6.37 kernels. Make sure you enable CONFIG_BKL on those kernels.
