I noticed something interesting about kernel 3.6.5-rt14.

spinymouse@email-addr-hidden:~$ uname -a
Linux qrc 3.5.0-17-lowlatency #18-Ubuntu SMP PREEMPT Tue Oct 9 20:04:43
UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

spinymouse@email-addr-hidden:~$ /etc/init.d/rtirq status | grep radeon
  768 FF 50 - 90 0.0 S irq/18-radeon
spinymouse@email-addr-hidden:~$ /etc/init.d/rtirq status | grep irq/18
  777 FF 85 - 125 0.0 S irq/18-snd_hdsp
   56 FF 78 - 118 0.0 S irq/18-ohci_hcd
   58 FF 77 - 117 0.0 S irq/18-ohci_hcd
  768 FF 50 - 90 0.0 S irq/18-radeon

spinymouse@email-addr-hidden:~$ uname -a
Linux qrc 3.6.5-rt14 #1 SMP PREEMPT RT Fri Nov 2 21:36:37 CET 2012
x86_64 x86_64 x86_64 GNU/Linux

spinymouse@email-addr-hidden:~$ /etc/init.d/rtirq status | grep radeon
  807 FF 50 - 90 0.0 S irq/43-radeon
spinymouse@email-addr-hidden:~$ /etc/init.d/rtirq status | grep irq/18
  832 FF 85 - 125 0.0 S irq/18-snd_hdsp
   58 FF 78 - 118 0.0 S irq/18-ohci_hcd
   60 FF 77 - 117 0.0 S irq/18-ohci_hcd

Unfortunately it didn't solve xrun issues for the RME card. However,
the kernel does switch to another IRQ for the graphics, for all other
kernels on different distros, the graphics always gets IRQ18, also if I
switch the integrated ATI with a Nvidia.

Regards,
Ralf
