--num-threads=1. The reason is
that when --num-threads is specified,
makedumpfile uses one producer and one consumer thread. So even with
--num-threads=1, multithreading
is still in effect.

crash: cannot read hardirq_ctx[930] at c0001e2d2fe48000
crash: compressed kdump: uncompress failed: 0
```
Should we include the above crash logs or the you observed in this
commit message for easy reference?
I tested this fix on high-end Power systems with 64TB of RAM as well as
on systems with lower memory, and everything is
working fine in both cases.
Thanks for the fix.
