Hello, I notice that during sleep/wakeup au1000_lowlevel_probe() tries to access to variables arcs_cmdline,prom_envp & Co.. This sometime does an oops. What I like to understand is if I simply have to skip accessing to these variables during wake up or I have to save them during system boot or what...?
