    Does that happen frequently, or only once?
    If it happens frequently, then you could try to replace the WQ_BUG with

    extern void show_stack(unsigned long *esp);
    #define WQ_BUG() do { \
    printk("wq bug!.\n"); \
    show_stack(NULL); \
    __sti(); \
    for(;;); \
    } while(0);

    [untested]

    It _seems_ that the stack pointer got corrupted, and thus the kernel
    couldn't recover from the oops
