Hi
I just installed ubuntu 9.04 and have a problem with my
/etc/init.d/realtime script. I have something like this:
chrt -f -p 40 `pidof "IRQ-17"`
But it doesn't work because 'pidof "IRQ-17"' returns nothing:
atte@vestbjerg:~$ pidof "IRQ-17"
atte@vestbjerg:~$
How/where can I see that name irq 17 now has?

IRQ processes only exist on kernels with realtime patch, and only when
the "threaded IRQ" option is ticked in the .config.
maybe you are using a standard kernel?

Indeed.
So here's an argument for patching the kernel (lot's of people have been
reporting "good enough" performance with stock kernels).
