Let me know if you need additional information. Found the root cause. As suspected, it's somewhat of a timing problem. :-) When constructing the corresponding initramfs, dracut queries the module via modinfo -F for firmware as required by the module. B43 only reports a small, generic set of files due to the b43-fwcutter issue, so some firmware files are subsequently missing from the initramfs image. This is the issue. Workaround: defer firmware loading until the real FS is mounted via eliminating /usr/lib/firmware/b43 from the initramfs image (this is what the previous kernel initramfs does as outlined above). Brutal hack: "modprobe -r b43; modprobe b43" in rc.local and enabling the systemd.rc-local service (as the root FS is mounted at that stage). Maybe upstream could look at option #1? *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are 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 24 kernel bugs. Fedora 25 has now been rebased to 4.10.9-100.fc24. 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 26, and are still experiencing this issue, please change the version to Fedora 26. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously. |
