Description xavier Tarteret 2015-10-25 11:25:39 CET
Hi,

I have fresh installed the last Mageia version on my Dell Inspiron 6400, which is a 32 bits computer.

When i go into the dmesg, i can see some failure, one of them is relates on 
Failed to find cpu0 device node

It appeared at the end of Mageia 4, so maybe it came with a new kernel version, i dont know.

Here is the dmesg log attached with this bug

=> To reproduce it, i only have to boot, it always appears.

Is there any kernel option to change for this computer?
Currently it starts with 

title linux
kernel (hd0,0)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=58815e6f-1297-49ad-ad0f-8e3f38baf1f4 splash quiet noiswmd resume=UUID=b13e77fa-10f0-4cf5-9347-4b874e2ca0a3 vga=788
root (hd0,0)
initrd /boot/initrd.img

the kernel is => 4.1.8-desktop-1.mga5

Here is an extract of the dmesg logs

[    1.146685] agpgart-intel 0000:00:00.0: detected 8192K stolen memory
[    1.146934] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xc0000000

I've seen this a lot too.  It's probably meaningless, but it should be silenced.
