Hi there, from time to time my laptop (a Lenovo ThinkPad T420s) freezes while attempting to enter S3. From the dmesg output it seems that it is encountering a timeout while attempting to suspend the NEC Corporation uPD720200 USB 3.0 controller: xhci_hcd 0000:0d:00.0: WARN: xHC CMD_RUN timeout suspend_common(): xhci_pci_suspend+0x0/0x40 [xhci_hcd] returns -110 sdhci-pci 0000:05:00.0: PCI INT A disabled pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -110 System details: uname -a: Linux orion 3.2.6 #24 SMP Mon Feb 20 20:08:45 CET 2012 x86_64 x86_64 x86_64 GNU/Linux lsusb -v: https://secure.tgbyte.de/dropbox/Aiwir1oo-lsusb-v.txt lspci -v: https://secure.tgbyte.de/dropbox/Aiwir1oo-lspci-v.txt Any ideas?
