Description of problem: I have a Nokia-6021 that I can connect to my Dell laptop via USB and a CA-42 canle using gnokii-0.6.14 software. This worked fine with Fedora Core 6. After upgrading to Fedora 7 I'm having connection problems. I decided to install kernel-2.6.20-1.2962.fc6 on my fc7 system next to the current fc7 kernel version. Using grub I can select which kernel to use when booting. This way I could make a comparison between the two. Conclusion: connection fails with kernel-2.6.22.1-41.fc7 and succeeds with kernel-2.6.20-1.2962.fc6. Version-Release number of selected component (if applicable): kernel-2.6.20-1.2962.fc6 kernel-2.6.22.1-41.fc7 gnokii-0.6.14-3.fc7 How reproducible: Always Steps to Reproduce: 1. connect Nokia 6021 phone with CA-42 cable to USB port 2. gnokii --identify 3. Actual results: gnokii needs a lot of time for retries and then returns several "unknown" results. Expected results: gnokii should return phone model type number. Additional info: If you have installed also the older kernel version, it is possible to have succes with FC7 kernel in one particular situation: step 1: When booting the computer select the 2.6.20 kernel version from FC6. step 2: connect the phone using gnokii and CA-42/usb cable. (works fine) step 3: reboot the computer, keeping the phone and cable connected step 4: now select kernel-2.6.22 from FC7 in the grub boot menu. step 5: try gnokii --identify again: IT WORKS !! step 6: disconnect the phone step 7: re-connect the phone step 8: try gnokii --identify again: IT FAILS AGAIN ! There seems to be some kind of problem with loading/unloading and initializing the proper drivermodule(s) in FC7 ?? I have attached 2 logfiles.

The test.fc6 and test.fc7 are packed in a tar.gz file.

What does output of 'strace gnokii --identify' look like when it fails?
Created attachment 168573 [details] output of "strace -ostrace_gnokii.log gnokii --identify"

Created attachment 172439 [details] output of "strace gnokii --identify" when using an older 2.6.20 kernel (from FC6): gnokii works !
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged.
As indicated previously there has been no update on the progress of this bug therefore I am closing it as INSUFFICIENT_DATA. Please re-open if the issue still occurs for you and I will try to assist in its resolution. Thank you for taking the time to report the initial bug.
