[LAU] Something interesting about kernel 3.6.5-rt14

I noticed something interesting about kernel 3.6.5-rt14. spinymouse@qrc:~$ 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@qrc:~$ /etc/init.d/rtirq status | grep radeon 768 FF 50 - 90 0.0 S irq/18-radeon spinymouse@qrc:~$ /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@qrc:~$ 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@qrc:~$ /etc/init.d/rtirq status | grep radeon 807 FF 50 - 90 0.0 S irq/43-radeon spinymouse@qrc:~$ /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.
