In a nutshell, Tried to install CentOS 6.4 on two different machines and it would fail at examining basic storage--usually crashing, sometimes just hanging. CentOS 6.3 didn't have the problem. After a great deal of googling and thinking, I realized the difference between the time I'd successfully installed 6.4 on the laptop and failed to do so was changing the filesystem of a Fedora install that shared the test laptop. If I use BTRFS on the Fedora system, the CentOS system won't install. If Fedora is using ext4, it installs as expected. Interesting that this is a regression on RH's part (I say RH because I had the same results with Scientific Linux, and regression because the issue doesn't occur in CentOS 6.3) The failure comes early, at examining basic storage. So, I realize it's a fairly unusual case, but figured I'd put it here for posterity. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6
