So far yes. I am now on 2.6.24rc2 and although the input device numbers steadily increase s2ram does reliably work even when done >10 times in a row and no problems with evdev devices not being available. However resume is slower as some ata device (I think my cdrom) is timing out. So it could be related to a too fast resume from suspend. So the problem may re-appear if matthew garrets fix for [PATCH] Don't fail ata device revalidation for bad _GTF methods will be committed. Is there still a need to do tests with the printk's in 2.6.23?

2.6.23: no more free evdev devices - evdev leak?
Dear all, whenever I do a suspend resume cycle the input device's numbers are increased until I finally run out of evdev devices. Is this a kernel problem or some userspace program (udev/...) creating new devices all the time? here is the dmesg: Soeren input: Power Button (FF) as /devices/virtual/input/input0 input: Lid Switch as /devices/virtual/input/input1 input: Power Button (CM) as /devices/virtual/input/input2 input: Sleep Button (CM) as /devices/virtual/input/input3 input: Macintosh mouse button emulation as /devices/virtual/input/input4 input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.0/input/input5 input: USB HID v1.11 Keyboard [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.2/input/input6 input: USB HID v1.11 Device [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.0/input/input7 input: USB HID v1.11 Keyboard [HID 05ac:1000] on usb-:00:1d.3-1 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.1/input/input8 input: USB HID v1.11 Mouse [HID 05ac:1000] on usb-:00:1d.3-1 input: appletouch as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.1/input/input9 input: Video Bus as /devices/virtual/input/input10 input: applesmc as /devices/platform/applesmc.768/input/input11 input: appletouch disconnected input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.0/input/input12 input: USB HID v1.11 Keyboard [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: appletouch as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.1/input/input13 input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.2/input/input14 input: USB HID v1.11 Device [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.0/input/input15 input: USB HID v1.11 Keyboard [HID 05ac:1000] on usb-:00:1d.3-1 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.1/input/input16 input: USB HID v1.11 Mouse [HID 05ac:1000] on usb-:00:1d.3-1 input: appletouch disconnected input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.0/input/input17 input: USB HID v1.11 Keyboard [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: appletouch as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.1/input/input18 input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.2/input/input19 input: USB HID v1.11 Device [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.0/input/input20 input: USB HID v1.11 Keyboard [HID 05ac:1000] on usb-:00:1d.3-1 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.1/input/input21 input: USB HID v1.11 Mouse [HID 05ac:1000] on usb-:00:1d.3-1 input: appletouch disconnected input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.0/input/input22 input: USB HID v1.11 Keyboard [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: appletouch as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.1/input/input23 input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.2/input/input24 input: USB HID v1.11 Device [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.0/input/input25 input: USB HID v1.11 Keyboard [HID 05ac:1000] on usb-:00:1d.3-1 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.1/input/input26 input: USB HID v1.11 Mouse [HID 05ac:1000] on usb-:00:1d.3-1 input: appletouch disconnected input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.0/input/input27 input: USB HID v1.11 Keyboard [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: appletouch as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.1/input/input28 input: Apple Computer Apple Internal Keyboard / Trackpad as /devices/pci:00/:00:1d.0/usb2/2-2/2-2:1.2/input/input29 input: USB HID v1.11 Device [Apple Computer Apple Internal Keyboard / Trackpad] on usb-:00:1d.0-2 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.0/input/input30 input: USB HID v1.11 Keyboard [HID 05ac:1000] on usb-:00:1d.3-1 input: HID 05ac:1000 as /devices/pci:00/:00:1d.3/usb5/5-1/5-1:1.1/input/input31
