Seems the reason why this happens is explained in commit 8c197ccfb600 ("ARM: OMAP4460: Workaround ABE DPLL failing to turn-on")

This doesn't really sound related to me. The problem described there is apparently a failure to get a usable interface clock to certain timers when the ABE PLL isn't enabled, and the workaround is to always enable the ABE PLL (and rely on its autoidle feature to disable it when unneeded). Our problem is that enabling the ABE PLL under certain conditions results in its state machine getting stuck.
