Something change or would anyone have any ideas of what might have happened, and how to fix? I can't help with your problem, but it's odd that I had something similar happen the other day. I was making a fresh installation of Gentoo on an oldish dual-Opteron box, booting rescue-CD and using two SATA disks with md RAID and LVM2. I'd spent the whole afternoon on this, as many steps are involved, and I'd eventually reached the installation of GRUB into /boot, when I got an error saying that /boot was mounted read-only.

Re: [gentoo-user] /usr/src/linux gone
As someone said above, a possible cause is that /usr/src was a mount point, maybe with -obind, or even a symlink. Many people do this to handle kernels manually on their own $HOME directory (I do it this way myself). Another random cause I can think of would be some of the cruft cleaning scripts that there are around and that are not part of Gentoo. On a more paranoid though, it could also be a rootkit, or maybe your box was hacked.
