Doesn't happen to me.  Maybe you should provide some more details and
someone can resolve that issue for you.



Well, thanks for the offer but I doubt it :-( The first reported incident, is the posting below;

https://www.redhat.com/archives/fedora-list/2005-May/msg04057.html

kernel-2.6.11-1.27_FC3 destroyed my sound configuration.

   * From: "Erik P. Olsen" <erik epo dk>
   * To: Fedora Mailing List <fedora-list redhat com>
   * Subject: kernel-2.6.11-1.27_FC3 destroyed my sound configuration.
   * Date: Fri, 27 May 2005 23:52:07 +0200

I upgraded my kernel to the subject version on May 24. In that very
moment all sound stopped on my system (only the hiss from the fans are
still there). I can see that modprobe.conf was also changed at that
time. I have restored the previous modprobe.conf but that only allowed
alsamixer to work, still no sound so apparently more damage was done.

I assume I have to reinstall/reconfigure alsa, but why did it happen and
how can I prevent this from happening next time I upgrade the kernel?

Note, that there was no response to this guy's post :-( Now, the very same thing happened to me. I was fortunate enough to have a backup of /etc/modprobe.conf on a SCO Open Server box attached to my LAN. Overwriting the hammered modprobe.conf with the backup copy worked for me. It's a good thing I had that backup because, I had pushed out that kernel update to ten clients with identical systems & their modprobe.conf file was hammered likewise :-(

Well, with the plethora of messages in the archive, if that is the only
one you find where modprobe.conf was corrupted then it does not seem
very prevalent an issue.

As I stated, this was the first incident. There are more in either July/August.

Personally I have never had that issue on any system I manage.

I understand your concern and am glad you had the backup, but what is
unique about your systems that made it happen to you when very few
others are reporting this problem?
It's not a concern anymore as it's a given, whenever there's a kernel upgrade, modprobe.conf will have to be overwritten with a backup. I now have a shell script that scp copies the backup to client boxes ;-) Nothing unique here, all systems are PIIs 300 Mhz 384mb RAM & have plain Creative SB-16 sound cards. I do find it odd, that this problem didn't occur on any kernel upgrade prior to kernel-2.6.11-1.27_FC3.

Is someone interrupting the update before it completes the configuration
step?  Is there something else that interferes? such as maybe the update
running and backups starting at the same time, etc.?

I always ensure that, whenever an update takes place, the FC3 box is the only one running.

Kernel updates seem to take a long time to finish the update.  At times
I have felt they were hung and have been tempted to kill the power since
the system was inaccessible at the time, ( although I never
have :-) ) .... but after waiting a long enough time they have always
finished for me.

I have Ultra DSL 3mbs & kernel updates take 3mins tops :-) The local Telco here is laying fiber down through the neighborhoods of my CTO & we'll be getting 30mbs speeds real soon :-)) Plus TV programing.
