I get those messages every time i shut down, so basically every day. Installed Ubuntu 16.04 on nvme ssd, that i installed into a msi notebook. Integrated intel (i7 7700) + dedicated nvidia graphics (gtx 1050)
PLEASE help me, turning off my laptop using the power button feels very unhealthy. Today i tried running lshw to give you some more information about my chipsets, etc. But the consequence was kind of a system freeze. Could not kill any processes anymore and one cpu core was at 100% - though htop did not tell me any process with 100% cpu load. Also networking and many other things were blocked. Last time i got: [992.132362] NMI watchdog: BUG: soft lockup - CPU#3 stuck for 22s! [gpu-manager:8250] [1020.132749] NMI watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [gpu-manager:8250] [1025.232819] INFO: rcu_sched self-detected stall on CPU ...followed by some irq stuff I also got this message with kworker instead of gpu-manager I highly suspect the nvidia gpu to be the issue here. Or some other hardware-based kernel issue. Or maybe nfs, i mounted 2 nfs shares on this machine for the first time, from which only 1 is available (i use this notebook in different offices). uname -r: Kernel: 4.10.0-27-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1530405 Title: NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
