Yes, that's basically why I don't use it. But the reason I was
considering it conditional on a config option is that Qualcomm
has a crash analysis tool that expects a BUG() call to stop the
system so its instant state can be captured. I don't use this
tool, and I might be mistaken about what's required.
What I would *really* like to do is have a way to gracefully
shut down just the IPA driver when an unexpected condition occurs,
so I can stop everything without crashing the system. But doing
that in a way that works in all cases is Hard.
Do you have any suggestions?
