If you can bisect the kernel and point to a particular commit that causes the increased packet loss, that would be very helpful. I know of no changes to any of the Realtek drivers that would cause these kinds of problems.

Larry

Thanks Larry - I have some idea of bisecting software, but no idea in regards to the Tumbleweed. Where can I find the various commits/versions to test as part of the bisection?

If openSUSE has a git repository for its kernels, I am not aware of its location. Perhaps someone will come up with that information.

You could clone the mainline repository from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git. Every change included in 4.7.X will be in that code. I would use the 4.7.5 configuration to build kernel 4.8 that is in that repo and test it. If you still get the packet loss, then use the commands 'git bisect start drivers/net/wireless/realtek/rtlwifi/', 'git bisect bad', and 'git bisect good v4.6'. Change that last one to whatever version you think is good.

That bisection will have roughly 5 steps to finish and should not take too long, even with the full configuration used in distribution kernels.

Larry

I keep getting errors when trying to star the git bisect.

Here is what I get:

git clone git://kernel.opensuse.org/kernel.git -b stable Cloning into 'kernel'... remote: Counting objects: 6374859, done. remote: fatal: inflateInit: out of memory (no message) remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed

how can I get around this error, maybe a git option to not compress or some such thing?

Strange, I don't get that error. You can try https://github.com/openSUSE/kernel.git instead.

Thank you in advance for your help,

Your configuration is faulty. I recommend using the one from openSUSE. You can find that in /proc/config.gz from a kernel that boots correctly, or in /boot/config-XXXX, where XXXX corresponds to the latest Tumbleweed kernel.

The correct command is "make xconfig", but the errors are due to revisions in make. The fix was made in commit 31110ebbec. If you want to try to work around that issue, then do the following: git bisect reset git show 31110ebbec > patch_31110ebbec git bisect start git bisect bad v4.6 git bisect good v4.5 make xconfig At this point, you will not get the Makefile error and you can make sudo make modules_install install and test the generated kernel. If you do get the Makefile error following a bisect step, then patch -p1 < patch_31110ebbec make xconfig sudo make modules_install install patch -p1 -R < patch_31110ebbec That restores the kernel source, which will be needed before the next bisection step. This procedure is complicated, but you should be able to handle it.

The bisect is done - I think. In addition to the bug with the Makefile, I also kept running into a kernel bug that kept causing segfaults in wpa_supplicant.

You should skip commits that you can't test with $ git bisect skip man git-bisect has more details. Robert -- http://robert.muntea.nu/ -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Thanks Robert, I did now know about bisect skip. Thanks Larry for trying to reproduce the issue. All I do to reproduce it is to ping a node over the wifi - 100 pings shows about 50 to 70% drops ... -- --Moby They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Sorry to take so long to get back to you. For some reason, the RTL8188EE card would not work in my laptop that I use for testing other Realtek devices. To get around that, I had to borrow a suitable laptop. I still do not know which commit is causing the problem, but I can duplicate the problem. As a work around, you should do the following: git clone http://github.com/lwfinger/rtlwifi_new.git cd rtlwifi_new make sudo make install Since our last communication, Realtek sent me a bunch of changes that are just now being submitted to mainline; however, the above GitHub repo has all of those changes and they fix the RTL8188EE problem. You will need to repeat the make and make install steps every time your kernel changes.
