Firmware crash/lockup on WLE900VX.

This is with my somewhat modified ath10k driver (mostly just
additional printks as far as this firmware is concerned),
and standard upstream firmware running in AP mode.

I guess the interesting question to me is why we cannot read
the firmware dump area address?

It all goes down hill from there and soft resets fail to
resolve the issue.
