Disabling IRQ 5 message

My installation of Mandriva 2006 went fine until first my mouse worked, then it just stopped working. Well, I'm fine with using my keyboard for installation. So I proceed to the point where it says 'installing CK804 SATA driver' (nForce4 chipset). It just froze there. In text install mode I could see the error messages (among them: "Disabling IRQ 5" and "irq 5: nobody cared"), and couple of stack dumps off of 'sata_nv'. Switching the PCI PnP OS option in my BIOS didn't change anything, so I switched it back to what it originally was (off). So other users suggested these kernel flags:

linux union=yes acpi=off nolapic

That fixed the freezing part, but there's another problem. After I get past the freezing point using those options, then my keyboard doesn't work, so I have nothing to input with. Fedora 4 and SUSE 10 installed fine. Why is Mandriva having so many problems?
 
I have never heard of the 'union' option and looking through the kernel sources don't seem to mention it anywhere either. sata_nv is obviously one of the SATA drivers, if it's failing in Mandriva and not in other distros I would say Mandriva is applying a bad patch to their kernel. Have you checked their bug database?
 
Not sure. Anyhow finally I got the keyboard to work by adding 'irqfixup'. But then I reboot and the boot loader is essentially dead. I guess disabling apic made it not even detect the controller and thus not the drives or something. But then what was it installing to? Anyhow I just used my XP CD fixmbr/fixboot and I'm back in business for now but my SUSE 10 installation is gone now because I did a network install with it. I guess I'll avoid Mandriva for now; it probably uses too old of a kernel for my motherboard.

Does the mini boot CD (the one you download to do a network install) have the rescue function on it so I can install the GRUB boot loader again? My Fedora 4 CD 1 rescue just freezes up as well. Isn't getting my SUSE 10 back kind of hopeless if I didn't make a floppy for it? I'll just burn another DVD (this time of OpenSUSE 10) and use the rescue function on it (I'd like a hard copy of the install disc anyway). Would it be able to load the boot loader so it links to my old SUSE?

Moral of the story: don't use arguments if you don't know what they do.
 
Disabling APIC should just force it to use the old method for handling IRQs, it shouldn't have anything to do with your hard disk.

Sorry, I don't really know anything about the discs provided by Fedora, SuSE or Mandriva.
