Bug Description

This new laptop's wireless connection (HP Pavilion 13-b208tu, Broadcom BCM43142) is disconnecting every few minutes after coming up from a restart or shutdown. This corresponds to panics and tracebacks in the kernel log.

The laptop was freshly installed with Ubuntu 14.10 (Utopic), and disconnections were seen. I then upgraded it to Ubuntu 15.04 (Vivid developement release), and am still experiencing the problem. The Broadcom proprietary driver is being used, and seems to be the only one available for this device.

Stuart Bishop, as per http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-144120-1&cc=us&dlc=en&lc=en&os=4158&productOid=7597682&sw_lang=&product=7597681 an update to your computer's buggy and outdated BIOS is available (F.26). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status New.

Thank you for your understanding.

That was interesting. I eventually worked out how to get the BIOS updated (which requires a Windows 8.1 machine to unpack the BIOS, and combining it onto an HP_TOOLS UEFI diagnostics stick since any HP_TOOLS partition I had went with the Ubuntu install).

f.26 would not boot at all. Get to grub, choose recovery mode, and it gets as far as the second line about a RAM disk when it hangs and requires powering off. HP diagnostics seem to think everything was OK. I didn't try booting FreeDOS or a Win8.1 stick (I'm low on USB sticks).

Downgrading to f.24 got the system booting again. So I'm now slightly more up to date.

If people are running similar laptops with f.26 I'd be interested in hearing about it - perhaps somehow the flash went bad.

I'll twiddle the incomplete flag on this bug after I've run with the f.24 bios for a bit.

Stuart Bishop, one thing to keep in mind as noted in the previously provided support article, is some BIOS updates change around things (ex. adding new settings without telling you, changing BIOS settings CSM+UEFI to Secure Boot in my situation with a Windows 8.1 laptop, or messing around with the /boot/efi/EFI/ folder).

Stuart Bishop (stub) wrote :

The failure to boot Ubuntu 15.04 with the F.26 bios was reproduced with a USB recovery (bypassing any mess the BIOS update did to /boot), and after checking all the bios settings (there are very, very few things to twiddle on this model).

With F.24, I am still seeing failures identical to the one in the bug description (apart from the bios revision). In addition, wireless fails to come back at all after a resume (but this looks like a different bug, as the traces involve bluetooth).

I'll set this bug back to confirmed, but I understand if it needs to go back to incomplete until I can get the bios updated to F.26

Stuart Bishop, given F.26 is such a pain, for now, let us move forward, and we can always circle back on it.

I saw a similar problems with 14.10. I do not know if the kernel logs were similar, but could try to capture one with a LiveCD if it will help. I only had 14.10 on there a few days before upgrading.

Router firmmware has been updated, although I don't think that can help us diagnose the fault.

I wasn't able to reproduce today through normal use, but am able to trigger a failure using suspend/resume. Is this the same bug, and maybe a pointer to an ultimate fix?

Stuart Bishop, introducing suspend/resume drastically changes the dynamic of this report.

Hence, was the original problem of "Wifi unstable, panics" only occurring after resuming from suspend, or did it happen when coming up from a restart/shutdown?
