Re: IRQ conflict

I've also saw the same issue with my shared IRQs (and also IRQ was shared with nvidia graphics card).

If you look in your dmesg, it suggests you to boot with "irqpoll" option.

As for me - this didn't help until I added also "noirqdebug".

After that I'm running already 6 days without problems and required reboots (before that I had to reboot every day).

If this doesn't help, I also saw suggestions to boot with "noapic" option (as non-preferred).

Hope, this will help you.

Hi
I installed recently RT Debian Wheezy kernel but the problem was the same two years ago with a non RT kernel (2.6)

Message from syslogd@xxxx at Apr 28 19:53:06 ...
kernel:[18398.556575] Disabling IRQ #17

IRQ17 seems shared between firewire and sound hdmi nvidia graphics card.
I see nothing in the bios that can be set, but at worst, disabling the firewire ....
What can I do to resolve this IRQ conflict?
Thanks in advance for your ideas
