[meta-xilinx] Problems booting

Wed Jan 22 05:08:48 PST 2014

Hi Nathan,

Here's some more info:

Yes I'm currently using a nfsroot.  I'm using the 3.10 Linux Kernel 
provided by the meta-xilinx layer.  I've added the following packages 
recently to my image
net-snmp-client net-snmp-mibs net-snmp-server I've noticed that the 
snmpd process hogs the CPU, I'm wondering if this is the problem. I've 
taken them out and it seems to be running ok again.

Here's the build header:
Loading cache: 100% |###########################################| ETA:  
00:00:00
Loaded 1736 entries from dependency cache.
Parsing recipes: 100% |#########################################| Time:

Parsing of 1349 .bb files complete (1348 cached, 1 parsed). 1736 
targets, 69 skipped, 0 masked, 0 errors.
NOTE: Resolving any missing task queue dependencies

... bunch of stuff to enable certain kernel modules relating to 6LoWPAN.
