Looks like the system eventually recovers from the EHCI issue
after about fivew minutes or so of spamming the logs. It seems
the ehci-omap errors are:
[62934.201538] ehci-omap ehci-omap.0: detected XactErr len 0/8 retry 31
[62934.201660] ehci-omap ehci-omap.0: devpath 1.3.7 ep0out 3strikes
[62934.201873] ehci-omap ehci-omap.0: reused qh ea5632c0 schedule
More data below.

Tony
