That says nothing (to me) about how it's configured... :-)

Valid HZ options are 100, 250, 300 and 1000, unless overridden by an
arch-specific Kconfig file. (AFAICS, only mips does this, offering 48, 100,
128, 250, 256, 1000 and 1024.)

I have one computer on which I use HZ=100; however, it has no DVB devices.

Never have a drink when you are feeling sorry for yourself.
