Hello,
I suddenly came across possible hang or sigfault condition for redboot
with no configuration stored in flash.
The current version of dns module has a default initialization of dns
domain as a pointer to zero.
As a result redboot hangs on boot on mips32 platform. I attached a patch
with possible solution, I hope it will be helpful.
Kirill.
