Description of problem: I am facing severe system lockups/freezes with all i686-Fedora kernels >= 4.10 up to 4.12.7 with both Fedora 25 and 26 upon network activity, on one particular machine (A Pentium III). Unfortunately I haven't yet managed to generate a log file containing the actual error message (I have photo of misable quality of it). Journald doesn't seem to catch these (Likely due to the lockup), they only appear on the console. The core part of the error seems to be this: ... Call Trace: <SOFTIRQ rtl8139:poll+0292&0x570 [8139too] ... From this, I presume the realtek rtl8139/8139too kernel driver to be broken (git log indicates it was applied untested patches). Version-Release number of selected component (if applicable): All kernels >= 4.10 How reproducible: Always. Steps to Reproduce: 1. Boot 2. Produce network load (e.g. run rsync) Actual results: Machine locks up. Expected results: Function. Additional info: Git commit 82c01a84d5a9bd3b9347bb03eed2f05bbccef933 from Linus' git (https://github.com/torvalds/linux) and adding it to Fedoras kernel seems to fix this problem for me (Tested with fedora-26-i386, not tested yet on x86_64 nor fedora 25). No idea about the actual origin of the bug. Given the nature of the patch, my gut feeling is "uninitialized variables" or "prototype mismatches".
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '25'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
