Fedora 2 x86_64 2.6.8 probs
 

I just updated to the latest kernel from Fedora, now my system won't boot! it says "Kernel panic unable to mount root fs"

What do you have in your lilo or grub configuration files? Also, what are your hard drive specs? Do you see any other kernels in the boot loader? If so, do you get the same error when booting off them?

Wow, lol I had no idea where to look for those things (/me is such a newb) I'm working on it and I'll post it all shortly. Also I'm going to make a serious effort to fix it by comparing the items in those files to the older kernel entry which still works. Wish me luck!

Well, I don't see anything wrong in grub.conf:

timeout=10
splashimage=(hd0,1)/boot/grub/splash.xpm.gz
title Fedora Core (2.6.8-1.521)
root (hd0,1)
kernel /boot/vmlinuz-2.6.8-1.521 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.8-1.521.img
title Fedora Core (2.6.5-1.358)
root (hd0,1)
kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.5-1.358.img
title Windows XP
rootnoverify (hd0,0)
chainloader +1


As for my hard drive specs, it's a Hitachi DeskStar 80gb 7200rpm SATA

40gb at the front is assigned to XP
39.25 gb at the back for Fedora Core
.75gb for swap

currently this little guy resides on /dev/hde

You are right: your grub does look okay. I think it is probably because of the SATA drive. I'm not exactly sure if SATA support is automatically turned on with rpm kernel installation, especially 2.6.8; I didn't notice the option when I compiled 2.6.6. If not, you might have to recompile the kernel. Good luck!
