Andre... thank you very much for letting me know about the patch. I have applied it because I have been suffering from occasional random loss of connectivity to my own wifi routers. I have not yet encountered another router that triggers the original crash that I reported in this particular bug, so I am unable to test it fully. However, I hope it fixes the loss of connection problems at home. I will report my experiences against your bug after a few days of testing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1360783 Title: 14e4:4315 [Dell Studio 1558] Broadcom wifi crash in bcmwl-kernel- source cfg80211 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1360783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

That was definitely not my intention... I have NO evidence whatsoever that the new driver would fix my problem, i.e. kernel crashes in certain unidentified kinds of wifi hotspots. However, I have good evidence that the new driver installs and runs OK on the 14.04 LTS 3.13.0-40-lowlatency kernel. My suggestion is that it would be good from many aspects (especially support) to accelerate testing so the new driver could be added to the 14.04 repository without making anything worse. The advantage would be to have the same driver on several releases to shake out any remaining bugs. If my bug happened to be fixed as a side-effect, that would be nice. However, the main issue would be the standardisation of the latest driver across current ubuntu releases.

I haven't been lucky enough to find a wifi hotspot that triggers the crash yet. I decided to install bcmwl-kernel-source from the utopic repository, 6.30.223.248+bdcom-0ubuntu1. It installed on my 14.04 LTS lowlatency system without a problem, and is working fine on my home wifi network. I will use it for a couple of days and then install the new version on a notepad that runs 14.05 with the generic kernel.

oops! Even though I haven't been able to find a delinquent wifi router yet, it think the best overall approach will be to test the .248 driver and then release it on 14.10.

Brian Burch, thank you for providing the requested information.

Q1: Is this reproducible on your home WiFI network? I have 4 different home wifi routers (different hardware and firmware), and access to a 5th. It does not happen on any of them, which is a pity! Q2: Does b43 provide a WORKAROUND as outlined in... I regret not having seem that particular page before. Thanks, I will read it carefully in preparation for the next failure. Q3: Did this happen in a prior Ubuntu/wl version? I started using this driver version under ubuntu 13.10. I encountered the same external symptoms, but I had not done sufficient problem determination to know whether the same kernel crash was occurring. In other words, I can't be certain. The crash has certainly occurred with several different releases of the 3.13.0 low-latency kernel. Q4: Which WiFi hotspot would be most convenient for you to do testing on? None, I am sorry to say. All those I can be certain about are more than 10,000 miles away from me at the moment! However, I will look hard for one nearer - I will be travelling over the next few days, so I hope I can find one which is more convenient to test against. Q5: At the most convenient WiFi hotspot, could you please test the later version of wl in Utopic... Yes, but unfortunately I won't have time to download it before I leave. Thanks again, Christopher. I will let you know as soon as I have some new information.
