Problem: Usually (over 80% of the time) when I unplug my RTL8187L USB adapter, Linux locks up (freezes)
I've observed this problem with both VirtualBox (latest version) and Desktop Parallels.
This was not a problem with 2.6.34. It is a problem with 3.6.39 and .38. I compiled version 188.8.131.52 of the vanilla compat drivers and the problem still exists.
I would like to test this on bare hardware but I'd need an optical drive and blank DVD. If I find one I'll update.
