Bug Description
If I try to turn wireless off using Fn-F2 on my Asus Eee PC 701SDX the kernel panics. This is reproducible every time.
I can avoid the panic by manually removing the r8187se driver first (using rmmod). Then the kernel does not panic, and I can turn the wireless back on using Fn-F2 again, r8187se appears to autoload and everything continues to work fine.
I think that this problem the same as bug 522119, but a comment there says to file a new bug, so here it is.
I have also had a possibly related problem with the same r8187se driver causing the system to freeze if I boot it the system with wireless on and on AC power, suspend it, resume it and then switch to battery power. I have worked around this by adding SUSPEND_
I can provide more information / do more debugging if needed, I'm comfortable hacking kernel code. I have not been able to get the kernel to reboot after panic, and I presume this is why I'm not getting anything in /var/crash after installing linux-crashdump. Setting /proc/sys/
