Hello, Holger, Shaohua. There's libata dock related bug report. http://bugzilla.kernel.org/show_bug.cgi?id=11703 What seems to happen is that if the user unplugs the ultrabay drive while the system is suspended, libata never gets notified of the change and tries to access the port during resume resulting in deadlock. Maybe something needs to be done during resume hook? Thanks. -- tejun -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
