Hi, I recently installed Arch Linux on an old laptop (Fujitsu-Siemens AMILO Xi 2550) and noticed that: - when booting Linux from the Arch ISO (kernel version 6.10.10) WIFI is working fine - after installing Arch Linux from the ISO and booting (kernel version 6.11.5) WIFI was not working properly By "not working properly" I mean: downloading small files or installing a few small packages was working ok, but when downloading larger files or installing larger packages with lots of dependencies, the connection would gradually slow down and eventually die. I reported this on the Arch Linux forum (https://bbs.archlinux.org/viewtopic.php?pid=2206757) and some helpful memeber suggested that this might be the commit that broke things: https://github.com/torvalds/linux/commit/02b682d54598f61cbb7dbb14d98ec1801112b878 An Arch Linux packet manager (gromit) helped me debug this issue by building a couple of kernels that I tested. - https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.12rc5-1-x86_64.pkg.tar.zst - https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.12rc5-1.1-x86_64.pkg.tar.zst The first one didn't work, but the second (in which he reverted the commit linked above) did fix my problem. So, I guess this commit should be investigated by those in the know. Thats why I also added Andrii and Kalle to CC as they are listed in the commit message. My network controller: Intel corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61) Kernel driver in use: iwl4965 This is my first kernel bug report, hope I did everything right :) I'm ofc willing to help provide more info and debug locally here to help solve this issue. Thanks and good night Alf :) -- "The generation of random numbers is too important to be left to chance."
