All this issues in the past happened because some very smart guys
decided to do random broken things from signal context. Which is why
this is extremely hard to trace down.

See patch-ad of the old driver, which essentially avoids float
arithmetic in signal context. It doesn't apply anymore due to the
structural changes though.
