Hi All, I'm sending out an email about this as I'm not 100% sure how to fix this. As a kernel-developer I usually build my own local kernels, since I'm also a Fedora developer I try to keep the kernel .config of my local builds synced with the Fedora kernel-configs. When grabbing the config from the kernel-core-5.11.0-0.rc6.141.fc34.x86_64.rpm pkg and comparing it to my local config I noticed this: # CONFIG_USB_RTL8152 is not set And I immediately thought that can't be right, that is used in my Lenovo Thunderbolt docking station gen 2. It took me some digging to figure out what is going on here: [hans@x1 kernel-ark]$ pwd /home/hans/projects/kernel-ark [hans@x1 kernel-ark]$ find -name CONFIG_USB_RTL8152 ./redhat/configs/common/generic/CONFIG_USB_RTL8152 [hans@x1 kernel-ark]$ cat ./redhat/configs/common/generic/CONFIG_USB_RTL8152 CONFIG_USB_RTL8152=m That looks good, but is not what is in the rawhide-build, digging deeper finds this: [hans@x1 rawhide]$ pwd /home/hans/projects/fedora/kernel/rawhide [hans@x1 rawhide]$ grep CONFIG_USB_RTL8152 kernel-x86_64-fedora.config # CONFIG_USB_RTL8152 is not set, or the RTL8153 device is not Which looks weird and then I found this, which explains everything: [hans@x1 kernel-ark]$ cat redhat/configs/fedora/generic/CONFIG_USB_RTL8153_ECM # CONFIG_USB_RTL8153_ECM: # # This option supports ECM mode for RTL8153 ethernet adapter, when # CONFIG_USB_RTL8152 is not set, or the RTL8153 device is not # supported by r8152 driver. # # Symbol: USB_RTL8153_ECM [=m] # Type : tristate # Defined at drivers/net/usb/Kconfig:631 # Prompt: RTL8153 ECM support # Depends on: NETDEVICES [=y] && USB_NET_DRIVERS [=y] && USB_NET_CDCETHER [=m] && (USB_RTL8152 [=m] || USB_RTL8152 [=m]=n) # Location: # -> Device Drivers # -> Network device support (NETDEVICES [=y]) # -> USB Network Adapters (USB_NET_DRIVERS [=y]) # # # CONFIG_USB_RTL8153_ECM=m The script which is creating kernel-x86_64-fedora.config from all the CONFIG_FOO files is picking up the line from the comment block because the line matches the standard "# CONFIG_FOO is not set" template (with extra text at the end). Interestingly enough, I also see this: [hans@x1 kernel-ark]$ grep CONFIG_USB_RTL8152 redhat/configs/kernel-x86_64-fedora.config CONFIG_USB_RTL8152=m So on the kernel-x86_64-fedora.config in kernel-ark things are ok, but in the kernel-x86_64-fedora.config file in distgit, rawhide branch it is not ok ? I guess there is some difference in how these are generated ?
