[1.] One line summary of the problem:
Kernel panic - not syncing: fatal exception in interrupt
 
 
[2.] Full description of the problem/report:
Paste the Bug Description and a link to your Launchpad bug report.
A Kernel panic occurs as fast as 89 seconds into runtime with the Ralink RT3573 v2.5 driver for the Linksys AE3000 USB Wifi adapter.

4 images captured with a camera of the kernel panic output are attached to this report:
1. Kernel panic output showing invalid opcode.
2. Kernel panic showing backtrace.
3. Kernel panic with APIC disabled (noapic)
4. Kernel panic with APIC enabled
 
[3.] Keywords (i.e., modules, networking, kernel): Please note, Kernel.org uses a different keyword system then the Ubuntu Tags system.
 
[4.] Kernel version (from /proc/version):
Linux version 3.5.0-22-generic (buildd@komainu) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #34-Ubuntu SMP Tue Jan 8 21:47:00 UTC 2013
 
[5.] Output of Oops... message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt). This is only relevant if you had a oops crash (ex. flashing Caps Lock light).
 
[6.] A small shell script or example program which triggers the problem (if possible).
