I am also affected by this problem (UBSAN errors and system freezes on heavy WiFi load, e.g. during large downloads or SpeedTest). My adapter is:
04:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Dual Band Wireless Network Adapter [14e4:43b1] (rev 03) I've built a patched version of broadcom-sta 6.30.223.271-23ubuntu1.1 that is currently in Ubuntu 24.04 repositories, using the adapted patch from comment #17 (thanks!) and the problems resolved. I'm attaching the patch I used, because the changes needed to apply to separate amd64 and i386 source trees and there was one conflict. I'm asking Ubuntu maintainers to apply the patch and release updated broadcom-sta packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2078697 Title: Ubuntu 24.04.1 (kernel ?) freeze/crashes when downloading using broadcom-sta package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/2078697/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
