I am using the vanila 2.6.3 kernel I compiled myself.  I know it is my error since I did not have this problem with the 2.6.3 kernel that was provided by Arch Linux.

this probably the relevant hardware:  AMD 3000+ on a A7N8X Deluxe (with nforce2 chipset)

Re: irq 7 disabled error

Did you compile in the nforce support?  Also, do you have acpi enabled (some motherboards need acpi to handle irqs properly)?

Re: irq 7 disabled error

I have both enabled.  For the nforce support I assume here is what you mean:
Device Drivers>ATA/ATAPI/MFM/RLL support>
[*] AMD and nVidia support

You wouldnt happen to know where I could find the .config file that was used to compile the kernel provided during the install process?  I could probably find my error refering to that

Thanks for your help

Re: irq 7 disabled error

Run abs, then it'll be in /var/abs/kernels/kernel26/config.

Re: irq 7 disabled error

I tihnk it may be fixed, at least nothing has happened yet.  I compared the two config files and the main difference I saw was that I disabled a lot of things like joysticks, a bunch of network devices, basically hardware I do not have and never will.

I decided to give Andrew Mortons Patchset a try since I have always had good luck with it.  I patched the kernel, made oldconfig (with the config file from abs), built the kernel now everything seems to be good

I dont know what I did wrong but all is good now which is the main thing

Thanks
