Hello,
I have a problem with USB on beaglebone crashing with 3.8.8 kernel
when a device is removed. I observed almost identical behavior with
USB wifi dongle, hub, SD card reader and RTL dongle. I tried kernel
from Angstrom 2012.12 and kernel patched with Robert's patch.sh script
and they both behave similarly. Kernel 3.2.42 from Angstrom 2012.05
works fine.
This is log trace after removing card reader:

Wifi dongle adds a whole bunch of lines line this one:

I'll appreciate any advice how to fix this problem.
regards,
