Internet access problem after disabling apic

Please try to give some coherent information:

What was the original problem you experienced (wouldn't load pages)?
How did you switch off ipv6?
What is it that you changed to true and what is about:config?
What error messages are you getting when unable to boot (try ALT-F1 during boot)?
Can you boot in recovery mode?

1.What was the original problem you experienced (wouldn't load pages)?
whenever i used to start ubuntu it would write connection etablished yet the FF won't load any pages.

2.How did you switch off ipv6?
I did three things
i.sudo gedit /etc/modprobe.d/bad_list/ and wrote the lines alias ipv6 off alias net-pf-10 off
ii.gksudo gedit /etc/modporbe.d/aliases file. followed by edited the lines alias net-pf-10 to alias net-pf-10 off
(then i wrote the command sudo update-modules)
iii. gksudo gedit /etc/modprobe.d/blacklist added blacklist IPv6.

3. What is it that you changed to true and what is about:config?
network.dns.disableIPv6

4.What error messages are you getting when unable to boot (try ALT-F1 during boot)?
no error messages and i am able to boot perfectly .what i said was after each complete perfect booting i need to reboot in order my FF to load pages though my net connects when i boot the first time itself

INFO: i run on DHCP

Perhaps also telling us what you meant by FF (is not Feisty Fawn but Fire Fox) would have been usefull......
Can you launch firefox in a terminal, with this command, and tell us the output:

firefox

Then try again with this option:

firefox -safe-mode

Also, paste here the result of a dmesg command.

i will answer you in two cases Case 1 after booting and Case 2 after rebooting.Yes FF is firefox.

1.AFTER BOOTING

firefox gives no result in terminal though the browser does open but doesn't load pages

firefox -safe-mode opens first a dialog box askling whether to disable plugins..then the browser which doen't load pages

dmesg gives

NOTE:if this helps you from the last two daysone out of 4 booting starts with the message
/dev/sda 8 has been mounted without check 33 times check enforced......
then everything proceeds normal;ly after the check

another strange thing which i forgot to tell you is suppose i am in ubuntu and i restart my computer and now boot in XP then my net in XP shows limited or no connectivity .but once i shut down and start my XP the connection is perfect

Can you paste here the output of these commands:

lspci -vnn
cat /etc/hosts
cat /etc/network/interfaces
ifconfig

Thanks.

i am posting the output after i REBOOTED and the FF loads pages...

NOTE: i run on ethernet via DHCP

don't know if thsi would help you but i recently added "noapic" to the grub boot benu besides "#defoptions=splash screen start" because
i was getting an error ATP-BIOS timer.....after adding it everything became fine.

I don't think this is the culprit, but it will not harm to delete these lines from /etc/hosts:

# The following lines are desirable for IPv6 capable hosts
 ::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Next time it will not connect to inet, can you try with this command (in a terminal or command prompt):

sudo /etc/init.d/networking restart

Check if after that it will connect and please paste here the output too.

i was not able to understand your previous post.i just started my computer then entered the lines
sudo /etc/init.d/networking restart
in the terminal first the connection was disconnected then it was reconnected but still FF wouldn't load any page .

well the result was
pardesi@pardesi-desktop:~$ sudo /etc/init.d/networking restart

I'm wondering if this could be a Network Manager problem, having manually fiddled with configuration files may have broken something.
Try uninstalling it with these commands:

sudo apt-get remove --purge network-manager network-manager-gnome

just unistalling would do or do i have to reinstall them if yes how??

Just remove it with the command I gave you and see how it goes. We can always install them back later.

no the network manager was uninstalled and then there was a dialog box which said network ...has not got the necessary files to run.the computer which tells u about neywork connection was removed from tray

sorry typo the first word of my previous post is yes the unistallation was perfect

i think the problem is with FF .now the same thing is happening in windows to after booting no net after rebooting there is net .

I doubt it is firefox. If you have the same isssue in WinXP it is more likely an hardware problem related to your network chip (or less likely the router).

so is there any other explorer taht i can use for ubuntu
NOTE:There was no problem in XP till today it was working fine till now....

no the problem does not persist in XP i just checked it now even my IE opens so the problem is surely with ubuntu

forget about the post "i think the problem is with FF .now the same thing is happening in windows to after booting no net after rebooting there is net ."
it's wrong

Can you paste here the output of this command:

cat /proc/interrupts

can i reinstall the network manager if it's not advisable then i won't do or rather can't do until u tell me how but the problem is in order to post what the terminal write when i enter a certain code i need to go to ubuntu type it in the terminal copy paste it ina open office and change that into a .doc format burn it into a dvd and open in XP and reply to you......

so nm is not necessary to acess the net i thought it was a must

yes you are right thanks ,thanks.... you have been exceptional....cheers Cesare...cheers ubuntu.....

but the ATP BIOS TIMER bug still appears in the start up... what should i do.

Thanks Cesare Tirabassi, that solved my question.

>but the ATP BIOS TIMER bug still appears

That is not important, the kernel will automatically switch to the TSC.
