Even with a Blade 1500, which is the closest match to your machine
that I have, and a kernel built with your configuration file I can't
reproduce this using r228583. I'd suggest to test with a kernel built
using an empty object directory and without any local modifications.
If that still doesn't solve the problem given that there isn't even
a backtrace I just can suggest to do a binary search for the offending
commit, probably accounting especially for the changes to the VM
within the window of revisions in question.
