Hanging on Enabling Swap Space during boot

[eddiebrodie]

On Centos 4.2 kernel 2.6.9.22

Intermittently during boot, the system will hang on "Enabling Swap Space". This is intermittent however. Sometimes it will happen 5 or 6times in a row, but then it will boot the 7th time without a problem.

When this happens sometimes, I'll try to boot into single user mode from Grub Boot Loader but for some reason while in the Grub Boot Loader kernel selection screen I cannot enter the 'e', 'a' or 'c' keys. The only key I can enter is 'ENTER' which boots my kernel (only one OS on this box).

So two questions:

1. Why is my system hanging on "Enabling Swap Space"?
2. Why can't I enter single user mode in Grub Boot Loader?

Thanks

Try to disable extra mounts (check /etc/fstab file) from mounting automatically. For, example, this can happen when the machine is configured to mount network share (Samba) when it boots, but the share is not available, or networking is not up yet or it isn't configured correctly.

Computer needs to know what it is and where it belongs to on the network. So, hostname, DNS, netmask, default route, and IP, all need to be set correctly.
