Web down after kernel update


Today I update our Fedora on our new computer useing Up2date.
After rebooting to the new kernel (2.6.12-1.1381 FC3smp) and no web browser will work.

When attempting to load yahoo, Konquor reports network not reachable. All others just ignore a request for a new page. Yet, I can ping and tracerought to yahoo. Same patern for all the other sites I tried.

Rebooting to the old kernel (2.6.10-1.770 FC3smp) and it all comes back. No other changes to the system.

What's up???

Are you correctly resolving the yahoo domain name from the command line whilst using ping and traceroute or is there a DNS issue? What are the proxy / gateway settings within Konqueror showing, and will websites load via Lynx on the command line?

Booting to the new kernel...
ping, tracerought, and nslookup work.
lynx, mozilla, konquor, and epiphany do not.

Booting the old kernel and everything works.

Thus, the problem is not DNS but specific to http.

This is just an idea: Did some update in SELinux also come with the kernel update? Might there be some security policy preventing this from working?

Someone on the Fedora mailing list suggested the following:

Try
# touch /.autorelabel
# reboot

(alternatively this can be done in system-config-securitylevel ->
SELinux -> Relabel on next reboot)

or something similar to:

# yum update selinux-policy-targeted

SELinux was having conniptions ater the update.

However, the system has gone live using the older kernel and I cann't touch it anymore.

So I guess the issue will have to be put to bed as it stands.

Thanks anyway.

Just as a reference to anyone who searches, I had the same problem.

I resolved it by removing the network card, rebooting and then configuring a new connection when Linux was back up.

Weird.....

I'm glad it worked for you, but that does seem like a bad suggestion. It is most definitely a software problem.

However following on your suggestion: Did you try removing the entire profile for the ethernet card and then recreating it?

Yes thats what I meant by "configuring a new connection". It may be a software problem but I am just passing on my own fix to the same problem I was experiencing....

Just to update....for future reference.
"Bugzilla Bug 169921 Browser does not load anything for 2.6.12-1.1378_FC3"
on bugzilla.redhat.com seem to pertain to my problem.
Something about SELinux but it is over my head.
I am guessing future updates will fix it.
