Latest l-o and usb gadget + NFS root problems

Latest l-o and usb gadget + NFS root problems

[Tomi Valkeinen]

Hi,

There seems to be something wrong with latest l-o, usb gadget ethernet
and nfsroot. I'm not sure when it broke, but 2.6.29-rc3 worked fine.
This happens to me with beagleboard and a non-public omap3 board:

g_ether gadget: high speed config #1: CDC Ethernet (ECM)
IP-Config: Guessing netmask 255.255.255.0
IP-Config: Complete:
     device=usb0, addr=192.168.2.15, mask=255.255.255.0, gw=255.255.255.255,
     host=192.168.2.15, domain=, nis-domain=(none),
     bootserver=255.255.255.255, rootserver=192.168.2.14, rootpath=
Looking up port of RPC 100003/2 on 192.168.2.14
Looking up port of RPC 100005/1 on 192.168.2.14
VFS: Mounted root (nfs filesystem) on device 0:12.
Freeing init memory: 140K
nfs: server 192.168.2.14 not responding, still trying
nfs: server 192.168.2.14 not responding, still trying
...

With the nonpublic board I was able to boot up occasionally, but it
failed after doing something heavier on the nfs filesystem.

Are you running with lockdep enabled or disabled?

I was using default beagle defconfig, plus gadget eth compiled into
kernel. DEBUG_LOCKDEP seems to be off.

I saw something very similar couple days ago on N810 and ethernet
gadget. What was weird that when connection jammed, then also localhost
stopped working. Unfortunately I didn't debug any further would it
happen e.g. using BT PAN connection.
