Re: threadirqs kernel parameter with standard kernels...

    Hello Brendan

        
        Once again many thanks for your speedy responses.

        
        I am not a programmer, but I assume the kickstart file is used
        by anaconda for the hard disk installation.

        
        Looking at https://linuxmoz.com/centos-kickstart-guide/ which
        describes multiple laptop installations of fedora, it would
        appear that it is possible to pass a bootloader append option
        like:

          
          bootloader --append="threadirqs
            rhgb quiet"

        
        What I don't know is whether the /etc/default/grub is modified
        when the kickstart file is processed.

        
        Also, in the kickstart file a post configuration is run which
        adds users to specific groups.

        
        Again, what I don't  know is whether /etc/default/useradd is
        modified when the kickstart file is processed.

        
        Anyway just some ideas...

        
        Cheers, Simon

      Hello Brendan
          

          Many thanks for your quick response.
          

          The fc 21 JAM Live iso when burned on to a dvd definitely
          boots with the
          

          treadirqs parameter - rtirq functions correctly.
          

          I have made two installation onto hard drives from the same
          DVD and both
          

          installations started without the threadirqs parameter - the
          sound
          

          devices were not assigned irqs.
          

          Also, the users created on both hard drive installations were
          not
          

          automatically assigned to the jackuser and pulse-rt groups.
          

      This is a limitation of kickstart. We weren't able to do this
        at install time, only for the spin user when running in live
        mode.
        

      Should the users be assigned to any
          other groups or are there any other
          

          tweaks I should take care of?
          

        The 'realtime mode' section serves as a checklist of sorts, but
        looks like you have most of it covered:
