Hi paul, 

I am able to reproduce the issue. I am seeing the timeout prints for
i2c, gpio during bootup. I ll check why softreset is failing.

[    0.208892] omap_hwmod: i2c1: softreset failed (waited 10000 usec)
[    0.223114] omap_hwmod: i2c2: softreset failed (waited 10000 usec)
[    0.237335] omap_hwmod: i2c3: softreset failed (waited 10000 usec)
[    0.251525] omap_hwmod: gpio2: softreset failed (waited 10000 usec)
[    0.265594] omap_hwmod: gpio3: softreset failed (waited 10000 usec)
[    0.279693] omap_hwmod: gpio4: softreset failed (waited 10000 usec)
[    0.293762] omap_hwmod: gpio5: softreset failed (waited 10000 usec)
[    0.307861] omap_hwmod: gpio6: softreset failed (waited 10000 usec)
