Hi,

thanks for the infos.

btw: i use:

chrt -f -p 99 `pidof "IRQ 5"`

for example (chrt commandline parsing is kinda braindead). It seems to work: 

~$ ps -cmL `pidof "IRQ 5"`
  PID   LWP CLS PRI TTY      STAT   TIME COMMAND
  110     - -     - ?        -      0:00 [IRQ 5]
    -   110 FF  139 -        S<     0:00 -
