Unable to find root partition after new motherboard
I just installed a new motherboard and connected the sata hd with my Arch install on it. Arch boots fine until it tries to mount /dev/sdb3, the root partition which it says it can't find, and then drops to a ramfs shell. I'm not quite sure what to do about it beyond looking for a live cd.
The error is "ERROR: Unable to determine major/minor number of root device '/dev/sdb3'."
Edit: Fixed now. It turns out there was a problem with the kernel. Installing the kernel26-lts fixed everything.

Re: Unable to find root partition after new motherboard
I'm guessing that it was the process of rebuilding your kernel images that fixed it, not the lts kernel. Do a pacman -S kernel26 and I think you'll have no problems booting into the current kernel once mkinitcpio runs.
