failed to boot master image on snowball02

[Yongqin Liu]

It seems that lava-dispatcher failed to boot master image on snowball02.
job: http://validation.linaro.org/lava-server/scheduler/job/3972

there are some strange points:
1. the master images seem has been booted up, but the hardreset has been done:
    root@master:~# <LAVA_DISPATCHER>2011-11-19 07:40:06 AM INFO: Perform hard reset on the system
2. the hardreset on snowball seems need manual input:
    Press <ENTER> to continue...export PS1="$PS1 [rc=$(echo \$?)]: "cu: Got hangup signal Connected.
3. the failure of boot_master_image is not been processed.

job http://validation.linaro.org/lava-server/scheduler/job/4070 seems the same

Lets retry this to be sure, but I think #2 is fixed since you did this test. We could still need some configuration on the snowball side to make this work. Assigning to chithu since he already has the related blueprint to ensure lava is working properly with snowball.
