Airtel GSM internet connection freezes system

The wvdial config file
Description of problem:
After connection phone, if i select auto mobile broadband gsm connection my system freezes and I have to reboot.
Version-Release number of selected component (if applicable):
I am on Fedora x_86_64. All latest updates. The phone is Nokia 5300 xpress music.
Steps to Reproduce:
1. Connect phone
2. Select the auto mobile broadband gsm connection
Internet Connection should be established.
As a workaround I configured wvdial to do the work for me and I am using it. But the dns servers returned are not being used then. I have to force all applications to use some open dns server. Thought it works fine in my vista.
When you say "freeze", you mean your mouse cursor does not move, you cannot hit Ctrl+Alt+F2 to switch to a virtual terminal, etc?
Yes. Mouse and keyboard stop responding. I waited for more than five minutes. Even Ctrl+Alt+F2 does not work--The only thing that comes to my mind is removing power and rebooting.
Can I not instruct nm to use the wvdial configuration and also make use of the dns server ip provided by my gsm isp?(In reply to comment #1)

Ok, this is a kernel hang that should be fixed in the kernel driver. What kernel are you running? "uname -a" from a terminal will tell you.

When using NM, NM controls the mobile broadband connection. DNS server information can be entered in NetworkManager too, overriding the DNS your provider sends automatically. But the kernel bug needs to get fixed either way.
Linux localhost.localdomain 22.214.171.124-170.2.35.fc10.x86_64 #1 SMP Mon Feb 23 13:00:23 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
I am overriding the DNS settings in NM. But doing it each time is very inconvenient, I would very much love if NM could detect and use the values I get from wvdial automatically. Presently it is not even aware of the network that I establish using wvdial.
If you allow NM to control the connection, and do not use wvdial, then NM will use the settings sent from your provider via PPP. NM by definition does not know about connections it does not control.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
