Hi,

I just changed motherboards. I'm running CentOS. So of course when I
boot I get some sort of kernel panic. I cannot seem to find the right
fix. I've read up on finding the right drivers and all by booting
into rescue and using 'lsmod' and everything, but I am not sure if I'm
doing it correctly.

This is becomming a big problem......

Can anyone help me get this thing up and running please???

Thanks in advance!

Followup:

First, never let a friend buy your hardware. I ask him to get me a
new MB and the dork comes back with some FoxConn brand. Says it is
good because the xbox runs on them??? Have no idea and never used
them.

Anyhow, put the new board in, booted and got a kernel panic/not
syncing error. I thought that would happen as the drivers for the
controllers have changed. I followed some steps I found on booting
into rescue mode and rebuilding some initrd file......no good.

Any ideas? Will I just need to re-install? My last MB was an ASUS.
Perhaps getting another ASUS is the answer?

kernel panic - not syncing

If you could put a spare drive on the new MB, then minimally install to
that, you could see what's different in the initrd (assuming it even works).

However, the other thing it could be is that the new MB might need some
extra/different kernel parameters to work. "acpi=off" and "pci=nomsi"
are usually good clubs to beat a kernel into working on funky hardware.
They're not the only ones, though. There are lots of others to try.

... or some combination of the two ... or nothing.

If you can get as far as mounting the disks, you might need to
reconfigure modprobe.conf because of different hardware, too, although
kudzu can try to do it for you as much as possible.

Swapping more hardware isn't the thing I'd recommend considering first.
Swapping any MB, even if it's the same brand, is going to involve some
pain if you want to run off the old installation. Instead I'd recommend
first thinking about how much pain it will be to reconfigure your old
installation vs. building a new installation. I'm not advocating one
way or the other, because you know your details better than I do. I'm
advocating clearly weighing your options for a moment before you start
trying stuff just to start trying stuff.

Also:

Are your disks plain IDE or are they SATA? Were you using a 'special'
IDE driver on the old motherboard? Is the IDE controller on the new
motherboard a (different) 'special' one? (Special ones use a driver
other than the 'vanila' IDE (hd) driver, where the disks show up as
/dev/sd<mumble>, rather than /dev/hd<mumble>). It looks like there is a
hard disk driver in the initrd is not compatible with the new board.
If the disks are plain IDE, you can try going into the BIOS setup and
set the controller to Parallel IDE compatiblity mode if possible. This
will allow the kernel to use the plain IDE driver (compiled into the
kernel). This will get you up enough to update the initrd to use the
proper driver(s) for the new board.
