(Bad PHP is bad PHP, and SELinux does not necessarily help at all.) let's agree to disagree on this one :-) It's a different subject, and could be worth some time. For some reason, every Linux architect I've worked with, for over a decade, has decided on their own, decide to try to re-invent the File System Hierarchy from scratch. They each pick their own unique top level directory and litter it with their own special layouts, They won't use /usr/local, they won't use /opt, they fairly randomly re-assign what would be /etc directory contents or locations of /log, and do not get me *started* on all the various ways people lay out JBoss and its components. The results are predictably unfortunate interacting with SELinux. And the system vulnerabilities are usually far greater from the we trust the people we work with problems of storing passwords in clear text, refusing to apply published patches, and refusing to sanitize inputs for exposed services.

It is quite simple once you take the time to learn it (like everything in life) and we routinely deploy settings from cfengine for it. Unfortunately, I'm rarely in control of the deployment technology.: I'm too far into operations land to get the developer's testing environments to match production environments, and don't get me going on the randomization of functionality when the Java programmers start writing shell scripts. Interestingly, at SVNday in Berlin (an interesting Subversion conference), one company presented on completely relying on RPM for configuration management. Apache configurations and their Subversion source control integration to manage it. They included, locally built service tools, SSH configurations, all were hardcoded config files from RPM's that they could publish or replace on the fly. That could provide a workable SELinux managed environment, since the necessary ''%post installation steps could be well defined. -- groet, natxo

You might want to try the various atl drivers from ELrepo (elrepo.org).
They maintain current drivers for a lot of devices not generally
supported by TUV. I think you'll want kmod-atl2. If you find that none
of the ELrepo drivers work, it might be worth contacting them to get the
correct one built and added to the repository.
-Mark
I think the atl1c driver in kmod-compat-wireless might also support that
device, but first we really need to see the vendor:device ID pairing to
be able to advise further.
Please post the output from the following command (note this is on one
line):
for BUSID in $(/sbin/lspci | awk '{ IGNORECASE=1 } /net/ { print $1 }');
do /sbin/lspci -s $BUSID -m; /sbin/lspci -s $BUSID -n; done
Re: Error with 'irq_set_affinity_hint' while compiling compat-wireless
Thanks Mr. Mark! Your reply helped. Although there was no package kmod-atl2 in the elrepo, however installing kmod-atl1e from the same repo has enabled the system to detect the ethernet.

Re: Error with 'irq_set_affinity_hint' while compiling compat-wireless
Hi Phil,
As I noted in my earlier mail, the problem was resolved by installing atl1e
driver from elrepo. Also, before that I had already tried with atl1c but it did
not work.
Just in case if you do require (for curiosity or better solution) here is the
output from the command offered by yourself:

Looks like CentOS beat SL to 6.3 release
A particular client's mirror of CentOS exploded today with the unannounced CentOS 6.3 release. Congratulations to them for such quick work: is there a nominal release date for SL 6.3, so I can make sure to allocate disk space? I've actually got a mock setup, running SL 6.2, chewing its way through all the upstream vendor's 6.3 SRPM's for my knowledge and education. (Also, I publish Subversion and BIND updated SRPM tools over at www.github.com/nkadel/ and want to test them with new environments.
