kernel panic - not syncing: Fatal exception in interrupt
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
- In addition, a kernel bug report was filled out & attached to this bug
- report (bugreport.txt) i.e., /proc info, lsmod, etc...

Title:
Ubuntu 12.10 x86_64 3.5.0-22 kernel panic Ralink RT3573
Status in Linux Kernel Bugs:
Confirmed
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
1) Description: Ubuntu 12.10
Release: 12.10
2) Linux localhost 3.5.0-22-generic #34-Ubuntu SMP Tue Jan 8 21:47:00
UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
3) what is expected to happen is the kernel does not panic with the
Ralink RT3573 v2.5 driver for the Linksys AE3000 USB Wifi adapter.
4) What happens instead is a Kernel panic occurs as fast as 89 seconds into runtime. This backtrace was typed-out from a photo I captured via camera:
