I'm getting following OOPS on one of my Linux box.
Its related with one of a loadable module. To proceed further from here, I need generic
suggestion/pointers for debugging kernel OOPS.

Apparently 'schedule' is throwing this message:
if (unlikely(in_atomic() && !current->exit_state)) {
printk(KERN_ERR "BUG: scheduling while atomic: "
"%s/0x%08x/%d\n",
current->comm, preempt_count(), current->pid);
debug_show_held_locks(current)
;
if (irqs_disabled())
print_irqtrace_events(current);
dump_stack();
}
if (irqs_disabled())
print_irqtrace_events(current);
dump_stack();
}
