| |
This oops occurred a few days ago that is basically a very, very busy proxy. I'm new to kernel debugging, and I havent been on linux-kernel in a few years, but I thought someone here might be able to help find the cause.
Happy to provide any other information that might be needed...
Box is running an unpatched 2.2.21 kernel.
Thanks in advance, Aaron
