Title:
Kernel PANIC often when turning WiFi off
Status in linux package in Ubuntu:
Confirmed
Bug description:
When opening lots of network connections and disconnecting from WiFi I
get two light blinkning (CAPS LOCK light and the one to it's right) -
assuming kernel PANIC.
[As Google Chrome opens a lot of tabs, when starting, I've used the
trick of disconnecting WiFi for a while (and sometimes killing Chrome
processes, but not this time I believe, but it shouldn't matter), to
get it to avoid OOM.]
This is not the first time I've gotten a kernel PANIC this way or the
only kernel (may be a few versions back). I assume this is a bug in
the kernel (also), but also in (proprietary) wl:
