Issue 477: EHCI (internal USB) may be broken on 3.10ff kernels

Reported by Nikolaus Schaller, Aug 12, 2013

Something to test and check.

From the beagleboard mailing list:


I am trying to boot with a rootfs over nfs with a 3.10.6 kernel.
Looks like major changes were made for the USB subsystem, so I'm not 
too
surprised that it's not an out of the box experience.

... but ...

I saw this [1] on Robs trusty git repo, which makes me wonder if a 
3.10
kernel is at all possible to have networking compiled into the 
uImage.

Nope... With both v3.10.x/v3.11-rc ehci is very broken on omap3... 
If
you want usb/nfs/boot, stay with v3.9.x for now..

Regards,

test and close if no problems arise. Since we use the EHCI for the 
UMTS modem interface, the problems can only be seen for the Modem. 
So this is related to #478.
Relations: is related to 478
