From: Ákos Maróy on 23 Feb 2010 03:50 Hi, I wonder if this is the write place to post this issue to, but I have a proplem when trying go suspend or hibernate my system. after enabling pm_trace by: echo 1 > /sys/power/pm_trace and then issuing pm-suspend, I get the following in dmesg: [ 685.833275] PM: Entering mem sleep [ 685.833292] Suspending console(s) (use no_console_suspend to debug) [ 685.993399] pm_op(): usb_dev_suspend+0x0/0x10 returns -2 [ 685.993404] PM: Device usb2 failed to suspend: error -2 [ 685.993408] PM: Some devices failed to suspend [ 685.997009] PM: resume devices took 0.000 seconds [ 685.997169] PM: Finishing wakeup. this is on 2.6.32.8, but on 2.6.33-rc8 I get the same results. trying to find out what device this is: $ lsusb Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 0bda:0159 Realtek Semiconductor Corp.

Alan, > By the way, I noticed above that you have xhci-hcd installed. As far > as I know, that driver does not yet support system suspend. You should > try unloading xhci-hcd before doing the suspend (both with and without > CONFIG_USB_DEBUG). as I added xhci among the SUSPEND_MODULES for pm, I tried pm-hibernate after a successful pm-suspend. but this doesn't work, the machine just goes blank, and it doesn't power off. doing a power cycle boots it 'as usual'. how can one debug the hibernation process?
