I am trying to install Fedora 6 (x86_64) on a new Dell AMD 64 X2. I'm not getting very far. It's hanging on "io scheduler cfq (registered)"

Any thoughts?

I get the same problem booting from a usbflash drive. When I copy diskboot.img from the x86_64 iso, it fails at that message. When I copy diskboot.img from the i386 iso, everything works. Of course, I want to use the x86_64 iso. Did you figure out the problem?

No, I never did figure it out. The problem is that I'm installing from the CDs so I wouldn't know how/where to copy the diskboot.img file.

I ultimately went with the i368 install which is unfortunate but I had to get the server up. If anyone knows the solution I will reinstall the 64 bit version.

I updated the bios for the mobo I was using: Asus_M2NPV-VM. After the update, the FC6 install for x86_64 went smoothly.

I too tried to install Fedora 6 (x86_64) on a new Dell AMD 64 X2, and got the "io scheduler cfq" hang.
I find the fix given at
deekayen -dot- net -slash- node -slash- 1058
(strange format to get round restriction on posting URLs)
for Fedora Core 5 also works on Fedora Core 6.
The fix is to use the following command line to boot when the bootdisk first loads:

linux noapic acpi=off nofb

Thanks! I have the 32bit version installed now, but I'll give that a try at some point.

I had the same boot lockup problem on Ubuntu 6.10 (edgy) 64 bit.
I found various ways around it...
MSI K9NGM m/b (AMD64)
(1) Disable ACPI in BIOS - not very good because I want to monitor CPU etc.
(2) add "pci=noacpi" to the grub boot command - That works OK
(3) disable the IOAPIC function in BIOS - This is the method I am actually using. Everything seems to be OK.

One other problem... Soft reboots lock up during the startup. I need to switch off/on after running M$Windoze to get back to Linux.

How do I make these changes when booting from a CD during install? Is there something I type before "net install" or whatever the command is to start Fedora startup?

DaveVT5, (sorry I am not familiar with the Fedora CD boot)

To use this parameter when booting from a CD try typing "pci=noacpi" if there is any point when you normally just 'hit return', or if there is a point when you get the choice to select 'other options' you can try then.

If you are booting from GRUB (boot loader) you can...
(1) type 'e' to edit the currently selected choice
(2) select the Kernel line and type 'e' (to edit it)
(3) type "pci=noacpi" {return}
(4) type 'b' to boot.

If you actually install Linux to your HD then you can to manually edit (sudo gedit) /boot/grub/menu.1st to add this parameter to the Kernel line to avoid doing (1-4) every time.
