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
