Hi! I encountered that my system freezes when resuming my Lenovo X220t with integrated Wacom ISDv4 tablet from S3 suspend.
Currently running 3.17.0-rc6, I started to bisect and found that this commit causes the issue: commit 29b4739134c73a2873adec93346f09bb76d6a794 Author: Benjamin Tissoires <[email protected]> Date: Thu Jul 24 12:52:23 2014 -0700 Input: wacom - switch from an USB driver to a HID driver Running 3.17.0-rc6, right after boot, this shows up in the log: [ 25.843484] wacom 0003:056A:00E6.0001: usb_submit_urb(ctrl) failed: -1 [ 25.843531] wacom 0003:056A:00E6.0001: timeout initializing reports [ 25.843886] wacom 0003:056A:00E6.0001: hidraw0: USB HID v1.11 Device [Tablet ISD-V4] on usb-0000:00:1d.0-1.5/input0 [ 25.846036] input: Wacom ISDv4 E6 Finger as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.5/2-1.5:1.1/0003:056A:00E6.0002/input/input18 When suspending, the screen goes off and about 8 seconds later, the machine actually suspends. Right after the (instant) resume, I can see the frame buffer I had when suspending (X screen) for about 10 seconds. During that time, no sysrq works. After this short period, the tty1-framebuffer appears, with messed up linebreaks (no carriage returns occur any more), and the capslock-led starts blinking. Sysrq keys still don't work. The system is completely frozen. Running the kernel from the bisected first good commit, the suspend is faster (under 1 second) and the resume does not crash. I just saw the "HID: wacom: fix timeout on probe for some wacoms" mail, which probably has to do something with my problem. Any ideas?
