linux - Need noacpi in CentOS 6.4, not in RHEL 6.4

    I've been trying to fix a rather odd problem that I've seen on our new Dell R5500 (Xeon based workstations).

    We want to run CentOS 6.4 64 bit on them. We did a base install which worked fine, however upon a soft restart (ie shutdown -r now) the LEDs on the R5500 indicate a hardware issue once the OS triggers the actual restart (the power cycle after it's finished it's shutdown procedure).

    I worked around this by adding noacpi to the kernel boot paremeters. This means we can reboot OK, but obviously this means we miss out on the advanced power features - which feels a bit primitive for 2013.

    Anyway, I installed a copy of RHEL 6.4 64bit - which I understand should be functionally identical to CentOS - and we don't see the issue at all. Restarts etc all work as expected, and we have the advanced power functionality.

    Has anyone seen this issue before, or have any ideas where I could look for more information? If possible I'd much rather use CentOS over RHEL.

    Fedora does not correspond directly to RHEL or CentOS; RHEL is built from pieces of Fedora, but not the whole thing.

    The latest RHEL and CentOS versions are directly comparable, except for prerelease versions. Older versions of RHEL have a "u" to indicate the update release where CentOS has a "." to indicate the minor version.

    Also note that delays in having gotten CentOS 6 out mean that CentOS 6.0 is slightly ahead of RHEL 6.0, although the CentOS developers plan to have this straightened out with 6.1.

    There is no relation between fedora version and RHEL, Centos version. Fedora is a community project with a release in each 6 months. But RHEL and its clone Centos are enterprise-grade distributions with long release gap. CentOS is a clone of RHEL with branding/artwork etc removed from RHEL. Since the logo, artwork etc are the property of Redhat, it is not possible for a community distro to use that. CentOS removes the brading from RHEL and releases the Centos distro. Centos follows the same release cycle as RHEL but lags behind RHEL. RHEL 6 was released this year and CentOS will release version 6 in 2011.
