I was able to reproduce the issue on a stock Jessie install on a Vostro 1320 (featuring a BCM 3412). Kernel versions after 3.17 (including 3.18.12, 3.19.0, 3.19.6 and 4.0.1, at least these are the ones I checked myself) seem to have an issue which causes the kernel to lock up. BCM4331 causes an immediate freeze, whereas BCM 1312 (and as ralphb pointed out above BCM 4360) only show these symptoms after actual payload transmission. This goes for bcmwl versions 6.30.223.248 and 6.20.155.1.
I heard at a LUG meeting that Fedora 21/22 apparently contain special patches which at least support an MBP mid-2013. I will verify this and report results back asap. Given that the kernel maintainer closed this issue (a move which I can only follow partly as wl works fine on pre-3.18 kernels) and BCM chips are pretty popular among laptop manufacturers: Could somebody upstream please assign this and bump it up so that we can get a resolution quickly? More than happy to provide additional information in the meantime - just let me know what is needed (unfortunately, the wl driver doesn't seem to support debugging information generation beyond the usual). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1451789 Title: bcmwl causes system freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1451789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
