I'm unable to reproduce this bug:
$ lsusb
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n
Wireless Network Adapter
...
$ uname -a
Linux raspi3 4.8.0-1033-raspi2 #36 SMP Tue Jun 13 11:24:42 UTC 2017 armv7l
armv7l armv7l GNU/Linux
probably due to the slightly different chipset (CUS vs EUS).
Nonetheless, people have mentioned that the latest kernel fixed the panic for
them, can anyone confirm this?
At the moment of this writing, this is the latest Yakkety raspi2 kernel:
linux-image-4.8.0-1038-raspi2
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Changed in: linux-meta-raspi2 (Ubuntu)

Title:
Kernel panic when using rtlwifi since 4.8.0-1025 on RasPi 2
Status in linux package in Ubuntu:
Incomplete
Status in linux-meta-raspi2 package in Ubuntu:
Invalid
Bug description:
I have a Raspberry Pi 2 running Ubuntu 16.10 without problems. I use
wicd to let it connect to my WiFi with a RTL8188CUS USB dongle. And
there's a RTL2838 DVB-T USB stick attached to monitor airplane
positions for Flightradar24.
After updateing the kernel from 4.8.0-1024, which runs flawlessly, to
-1025, there's a kernel panic happening 10-20 seconds after booting up
to the login prompt. I thought the -1026 fixed that, but it's still no
worky. The trace is scrolling so fast I can't read anything but the
last page:

And then this block repeats with CPU3 and CPU0.
Going back to 4.8.0-1024 makes everything work again.
