Kernel Panic - not syncing

Trying to get Gentoo to boot on my HP dv7t. Getting a Kernel panic - not syncing. Using a live usb if that matters at all, don't think that's the issue though because I have installed Gentoo on other systems using it.

Thanks for any help.

Is there anything except "not syncing"? Like something with VFS or something?

I had those panics, too, sometimes. Cause was most of the times that I forgot to include support for the filesystem of /BOOT in the kernel.

You need to post the complete log.

Just take a screen shot off it and post it here.

As stated, the full error message is necessary to diagnose the problem. However, it is likely that you either neglected to build the necessary ATA support into your kernel, or that your fstab is incorrect. Please post the full error message, and your /etc/fstab.

boot a system rescue cd to a gui and network. (use rescue64 at the boot prompt if a 64 bit install.) Open firefox window next to the terminal window.
In the terminal, mount the gentoo partitions, nominally:

For anyone else who gets this. remember you can change the kernel option in grub on the fly by hitting 'e' at the grub menu. If the issue is just your 'root=' this might allow you to at least boot the system without having to do a chroot from a livecd or rescue disk (which I find rather annoying to do). Even if your fstab is wrong you will likely at least be able to get a maintenance shell depending on certain factors. Then you can fix the fstab and grub.conf by remounting the filesystem and editing accordingly. This saved me from throwing my laptop out the window on my most recent gentoo install.
