Looks good to me, except for the two ohci_hcd and the
nvidia threads.
I
don't see those when you start rtirq but they are
there when you
query
rtirq's status. Weird. Same issue after a reboot?
And this hdspm
device,
is that an extension card (PCI, PCIe)? If so you might
want to try
another slot because having it to share the same IRQ as your GPU
isn't
ideal. And maybe you could post or pastebin your
complete
/etc/default/rtirq file.
Best,
Jeremy
Jeremy, the bad is, that I don't have another PCIe x1 slot :(.
In my experience, restarting the script tries to raise
the priorities
of the threads in RTIRQ_NAME_LIST, but the ones which are already
raised aren't lowered even if you leave them out of the list.
Try rebooting the computer.
Cheers, Pablo
*reboot*
The reboot doesn't improve anything :(.
I'll build my own kernel within the next days.
Is there anything missing to work with boot option threadirqs?
Usually I use self build kernel-rt and the nv driver. Since the nv
driver is dropped, I'm using the proprietary and I have given up to edit
the nvidia drivers header or to fake the license, since both never
worked on my machine.

There's another issue, I've got 4GB RAM, but only 3.8GB are accessible,
resp. shown. 256MB are missing. I've got this for another install too,
while a PAE 32-bit kernel has no issue with the 4GB. No framebuffer, the
graphics has got it's own RAM.
CONFIG_PREEMPT_COUNT ???
Thanks and regards,
