I have a server that frequently hangs while rebooting. I see no errors, but during the boot process it stops at this stage:
Initializing hardware... storage network audio
The cursor sits just after the word "audio" and I have to do a hard reset to get out of it.
The boot message is a red herring, it really doesn't have anything to do with the audio.
It *might* have something to do with ACPI ... search the CentOS list archives for a thread with the subject "CentOS 4.2 hangs at power-on boot" from February 2006. I had the same problem, and in fact still do, though now it's intermittent.
Right. We've already determined that it has finished loading the audio by the time it prints it. The problem must be with something else that loads afterwards.
I have added some debugging output to /etc/rc.sysinit so that it prints the names of the other misc things it loads after audio. The next time it happens, I'll have a better idea of what causes it.

We had a similar problem with cpuspeed causing a hang on some (not all) Tyan K8SD Pro servers. But it happened later in the boot. It looked like it was happening when an ethernet interface was being brought up, but it was really cpuspeed, which was starting just before that. Also, it only happened on a clean "# reboot'. A cold power-up or a push of the reset button would not cause the problem. It might be worth seeing whether that is the difference in your case.
We just turned cpuspeed off. I don't think cpuspeed has started so early in the boot in your case, but it's something to look for. (See my message 08/08/06 to this mailing list, "cpuspeed causing hangs on warm boots".)
