I'm not sure what I'm doing here. I presume I need to use chrt to change the
priority, but am not sure of the correct syntax. The current pid for IRQ10 is
940.

Could you give me a line that will work for this pid, as the man page is
pretty hopeless with no examples, and about 3 hrs of googling turned up
virtually nothing.

Many thanks.

Nigel.
