Package: src:linux Version: 4.3.3-7~bpo8+1 Severity: important Dear Maintainer,
>From a clean install of Debian Jessie 8.3 on a Lenovo Thinkpad E460 (Intel Skylake gen.) I upgraded the kernel to 4.3 as made available in jessie-backports to enable WiFi/Bluetooth. Fast-forward to yesterday when I was preparing a LiveUSB drive, writing approx. 4GB of data using cfdisk, mkfs, dd and sync. Following the removal of of the USB device, I noticed very high CPU usage being caused by kworker and ksoftirqd. Using perf to log 10s of data and then reading the report, I noticed that xhci_hcd/xhci_hub_control was generating a LOT of work for the kworker (~42%). Guessing that this had something to do with the USB ports, I tried plugging in a USB device, and found that plugging in *any* kind of USB device caused the CPU usage to drop to ~0%. Removing the USB device again caused the CPU usage to go back to 100% (one core). The same result occured with all 3 USB ports on this system, with ~0% CPU usage with any USB device connected, 100% CPU usage when no USB devices are connected. The issue persists through reboots of the system. The issue persists down to atleast init level 3, and is also present when booting the system in "Recovery Mode". Booting the system with the older 3.16 kernel causes the issue to disappear, but then I lose WiFi/Bluetooth so that isn't an option. I have not found a workaround to this problem besides leaving atleast one USB device connected whenever I'm using the system. -- Package-specific info: ** Version: Linux version 4.3.0-0.bpo.1-amd64 (debian-ker...@lists.debian.org) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Debian 4.3.3-7~bpo8+1 (2016-01-19) ** Command line: BOOT_IMAGE=/boot/vmlinuz-4.3.0-0.bpo.1-amd64 root=UUID=8e8f14a8-cdb5-4d74-b834-369017c333fb ro initrd=/install/initrd.gz quiet ** Tainted: WO (4608) * Taint on warning. * Out-of-tree module has been loaded. ** Kernel log: [ 10.267305] [<ffffffff8140dbc8>] ?
