[Bug 1280642] Re: BUG: soft lockup - CPU#1 stuck for 22s! [kswapd0:31]

 

I am currently affected by this bug. I would like to help, but it's not
at all obvious to me what tools I would use to investigate this. I am an
experienced software developer, just not in the kernel, nor in the
kernel's debugging tools/process. I am subscribed to emails for this
bug, and would gladly do anything helpful to solve this as it impacts my
development.

Thanks,

Derrell
