Please provide the full output of dmesg from both a working and non-working kernel. *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 21 kernel bugs. Fedora 21 has now been rebased to 3.19.5-200.fc21. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 22, and are still experiencing this issue, please change the version to Fedora 22. If you experience different issues, please open a new bug report for those. Sorry, didn't intend to remove the needinfo flag. (In reply to Bjørn Mork from comment #3) > Sorry, didn't intend to remove the needinfo flag. Any success with Huawei E3372 in the meantime. I have a similar problem with a Huawei E3372. Yes, there is now a fix for E3372 modems in v4.2: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4a0e3e989d66bb7204b163d9cfaa7fa96d0f2023 It has been tested out with success in OpenWRT: https://lists.openwrt.org/pipermail/openwrt-devel/2015-July/034431.html I don't think it has been added to the stable queue just yet. But it is a nicely contained fix, so I believe this patch is a good stable candidate if it really fixes the problem. Hi all, Sorry, I was not able to get E3372 working neither on F20 nor any router as I wrote at the beginning and thought that the modem is damaged. Many thanks to Bjørn for the info that the bug should be solved in kernel 4.2 and I confirms that it is really resolved there and this post is written from F22 with kernel 4.2.0-300.fc23.x86_64 using E3372 for connection. Messages like this still appears in dmesg but it works: [ 222.050238] huawei_cdc_ncm 1-1.1:1.2 wwp0s26u1u1i2: kevent 12 may have been dropped So this bug can be closed with "resolved in F23". Thanks. Sorry, I don't get it. What needs to be done or installed in Fedora 22 to get the E3372 working? Could you please give some advice?

Hi Harald, I did it using this command: dnf --releasever=23 --enablerepo=updates-testing update kernel* It installed 4.2 kernel which solved the issue for me. Lukas Thanks, Harald |
