Red Hat Bugzilla – Bug 481401
PCMCIA Aircard no longer works after kernel upgrade (last working in 22.214.171.124-117.fc10)
Last modified: 2009-02-23 12:42:55 EST
Description of problem:
After upgrading to the 126.96.36.199-159.fc10 kernel (from 188.8.131.52-117.fc10) my PCMCIA aircard (Verizon PC5750) no longer works. Network Manager reports "Unable to connect" message (see attached log dump from /var/log/messages ). Attempt to use gnome-ppp fails as well.
Booting into the 184.108.40.206-117.fc10 kernel (on same machine) and both Network Manager & gnome-ppp are able to connect correctly
Version-Release number of selected component (if applicable):
100% time in 220.127.116.11-117.fc10
Steps to Reproduce:
1.Plug in PCMCIA card
2.Network manager automatically tries to connect & fails
3. Open Terminal - su gnome-ppp
4. attempting to run Setup -> Detect hangs gnome-ppp
5. ctrl-c required in terminal to end gnome-ppp
PCMCIA CDMA card unusable/fails to connect
partial log file attached.

Still does not work (same symptoms/errors) after updating kernel to 18.104.22.168-117.fc10.
Only official fedora repo's are used for yum updating. No third party repos are used.
Modified bug summary to be non-version specific.
Can you post the logs from a working kernel?

Dump from Working Kernel
ttyUSB0 will not work; the connection needs to be made using ttyUSB1
How do we tell this to NetworkManager?
I was able to successfully connect using gnome-ppp but only if I manually entered /dev/ttyUSB1 in setup (attempting to use detect still fails & hangs the system).
Network Manager is still unhappy (but I have to find the correct config info to modify).
Since it appears the naming conventions have changed in the kernel does this need to be listed as a bug in gnome-ppp & Network Manager?

> How do we tell this to NetworkManager?
I don't know why NM doesn't know to use /dev/ttyUSB1... I'll copy the maintainer.
Upstream patch that caused the problem is reverted in 22.214.171.124-170.2.14

Updated to Kernel 126.96.36.199-170.2.24.fc10.i686 this past weekend and aircard now works as expected (both with gnome-ppp and NM)
