crashed to text only screen, kernel panic

[Samantha]

I wasn't running anything other than Firefox, which had just been sitting stationary for about 10 minutes and then the screen went to some text only page. I only remember seeing the words "Kernel panic" in some of the lines. It's done it twice so far today. I'm not the most...tech savvy...person, so I'm not really sure how to fix this?

I don't even know if I reported the correct thing here : D

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Lars Renström (lars-renstrom)]

I also hade kernel panic crashes and noted that the computer locked as soon as my WIFI connected. I then removed the bcmwl-kernel-source package and everything now works as a charm. Maybe you have the same problem?

[Wolter HV (wolterh)]

Lars, which network controller are you using?

[Lars Renström (lars-renstrom)]

This is the output from lspci:

43:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)

[Christopher Townsend (townsend)]

Given that "kernel panic" was seen on the screen, I don't think this is a Compiz issue. Given that both people commenting in this bug have Broadcom cards, I suspect the problem is in bcmwl.

[Doug Gale (doug16k)]

I have almost the same issues, except I run Metacity, so it's not related to compiz, and in my case, the panic can happen at resume but it frequently happens when I (try to) restart or shutdown. It kernel panics with either black screen or text mode, with flashing numlock. Stack trace scrolls off the top, but the symbols clearly indicate it is executing in the wl driver.

My NIC is similar:
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
