Bug appears to exist upstream in version 3.11.0-031100rc6.201308181835.
Have added the above tags as requested. Basically rebooting into the new
kernel leads to the same issue with a complete freeze until the USB key
is unplugged and replugged. At that time, the system returns to normal.
I haven't had it lock up yet during normal use, only on reboot. Attached
is a syslog from an affected reboot.
** Description changed:
My server occasionally suddenly hangs, and the wifi network cuts out.
This is then only fixed by unplugging and replugging in the USB wifi
adapter in question, and then the system suddenly restores itself and
works again. When the system freezes, the whole input/output system
fails, and any plugged in keyboards will not work until the USB stick is
unplugged and replugged. This is a very frustrating bug, and has started
happening with significant frequency recently.
