That's way too old for upstream to do any meaningful debugging without
more specific information.  Kernel threads usually don't deal with
signals but there are a handful weird places in kernel which make use
of actual signals to affect the control flow.  ISTR modifying some so
that it's not too crazy but I could be misremembering....

Thanks.
