Here's the updated version (at the bottom of this message). Seems to work based on a quick test on 2430SDP. # shutdown -r -n now shutdown: sending all processes the TERM signal... shutdown: sending all processes the KILL signal. shutdown: turning off swap shutdown: unmounting all file systems umount: /debug: not mounted umount: /run/shm: not mounted umount: /dev: not mounted umount: /tmp: not mounted umount: /run/lock: not mounted umount: /run: not mounted umount: /lib/init/rw: not found Please stand by while rebooting the system.

This causes the variables "sys_ck_rate" and "curr_prcm_set" to be uninitialised on boot. On reboot, this causes the following error message to be displayed because the appropriate MPU clock frequency (derived from sys_ck_rate) cannot be found. "Could not set MPU rate to 4294MHz" Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the OMAP2420 and OMAP2430 clock initialisation code.
