With openSUSE 11.1, it was no problem to hibernate and thaw the system with the switch. I used KDE3 with KPowersave under openSUSE 11.1. Now with openSUSE 11.2, KDE4 and PowerDevil, it don't work anymore. I can hibernate, but thaw with the belkin switch connected freezes the system. The image is loaded successfully at the beginning, but immediately after this, the system freezes with a blank screen (only a nonblinking textcursor remains on the screen). /var/log/pm-suspend shows in the last line '+ /usr/sbin/s2disk --config /var/lib/s2disk.conf', so thawe even don't begin. I've a complete encrypted system (root and swap on encrypted LVM, home with encrypted containers), but that should not be the problem, cause without switch, thaw works (see below). I tried several things to solve the problem: - added SUSPEND_MODULES="hid_belkin usbhid hid" to /etc/pm/config.d/ (unload worked, but thaw didn't work) - wrote a hook script for /etc/pm/sleep.d/ to unload and load the modules 'manually' (unload worked, thaw didn't work) - used the hook script only for unloading the modules (unload worked, thaw didn't work) - unplugged the switch (USB-cable) before thawe (worked!) - switched the switch to the other connected computer before thawe (worked!) AND: s2ram (suspend and resume) with switch works out of the box! I assume, there is maybe something wrong with module usbhid, which is used by the FLIP component of the switch (and used also by a USB-mouse and USB-Cherry-Keyboard, which are both connected to the switch). lsmod | grep his says hid_belkin 2528 0 hid_cherry 2336 0 usbhid 51968 0 hid 46848 3 hid_belkin,hid_cherry,usbhid usbhid has three parameters: parm: mousepoll:Polling interval of mice (uint) parm: ignoreled:Autosuspend with active leds (uint) parm: quirks:Add/modify USB HID quirks by specifying quirks=vendorID:productID:quirks where vendorID, productID, and quirks are all in 0x-prefixed hex (array of charp) I don't know, how to use the ignoreled- and quirks-parameter and I'm not shure, if the use of them could be a solution. But from hints in the web, ignoreled is more powersave related and quirks is more for not loading usbhid under certain vendors and ids (is this right?). The next thing I found in web as a 'maybe solution' is the kernel parameter usbcore.autosuspend, but I don't know anything about this parameter. I'll be glad about any help.
