Dell XPS 13 (BCM4352) Crash when connecting wifi.

[dznn]

Hi,

I get a kernel panic when I connect to my wifi network. I was hoping someone here could help me solve it.

• I have the new Dell XPS 13 (2015), latest bios A03, with a Broadcom BCM4352 wifi adapter.
• Installed the daily of the Ubuntu Server image because I wanted a minimal install and I couldn't find minimal or netinstall iso's of the daily.
• Installed the bcmwl-kernel-source package which should support my chip from what I could find online.
• Used connman to connect.

The strange thing is, unless I was dreaming I think it did work right after the install, the first run before a reboot.

Kernel:
Linux odin 3.19.0-14-generic #14-Ubuntu SMP Mon Apr 13 22:18:24 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I logged the panic;
(dmesg log) http://paste.ubuntu.com/10831802/
(dump.crash) http://paste.ubuntu.com/10831804/
(dump) I have this too but it's 44mb, if required I'll upload it.

Thanks


--Edit--

If people suggest using the dkms package directly, it's broken;

Also this might be the bug I experience, but it happens every time for me:

The Arch wiki they link to says it's solved for the BCM4352 but I can't use the b43 driver because it doesn't support my chip yet;

This seemed to have been a connman issue. When using Wicd it doesn't happen.

something strange:
- '_ART package 0 is invalid, ignored' which seems related to android
- 2 'crashkernel=' set as boot parameters

This thread is very old and doesn't contain a solution.

something strange:
- '_ART package 0 is invalid, ignored' which seems related to android
- 2 'crashkernel=' set as boot parameters

The crashkernel parameter is required for me to log the kernel panic. I have no idea where the ART comes from (I do have the Android SDK installed but that's totaly unrelated).

your logs does not show other way to dig; maybe add 'debug' to the bootloader to get more details

Hi dznn,

I am looking to install Ubuntu on this laptop. You mentioned about the "daily Ubuntu server image", I presume it was the daily of 15.04 which is now fully released. Does the released version run well?
