This is alarming. Please add this patch to get the error code:
This is also alarming... Let's increase the timeout just for a debugging
purpose:
I've applied both patches. The new kernel log in its entirety resides
here:
http://pastie.org/1384896
Unfortunately seems like pastie.org is down:
503 Service Unavailable
No server is available to handle this request.
And the line of interest is
[ 2.085449] ehci-omap ehci-omap.0: failed to get ehci port1 regulator
--> 0
Unfortunately, I don't understand what an error code of '0' might mean
here, but it surely does something.
That's funny, 0 means "success", not sure why that branch is being
called.
I'll wait a bit until pastie is back, but if you could append to your
reply the output of dmesg | grep -i ehci I'd be glad.
I really appreciate your help, this sort of a bug that really stunned me.
I've noticed that the variable storing the error code is set to NULL
right before printing it out :(, so I corrected this mistake.
[ 2.065216] ehci-omap ehci-omap.0: failed to get ehci port1 regulator
--> -19
I also switched to pastebin, with the new, more meaningful dmesg:
