Does reverting this patch help? http://git.kernel.org/?p=linux/kernel/git/hpa/linux-2.6-allstable.git;a=commit;h=814eb57e1799337d9fbb68f5d838afa507dc014e > >> Hardware Environment:x86 ASUS M2N-E OK, this is an MCP61 board. We're now using softreset instead of hardreset on hotplug and apparently that doesn't work. Thing is that: http://bugzilla.kernel.org/show_bug.cgi?id=11195 reported that hardreset was borked on that controller.
