Sorry, but checking my logs my stuck message has not "[ksmd:64]" at the end, but something different, I think "js" something. Right now I don't have any to put the exact string.
I keep getting lockups with the 4.10 kernel series, I've updated to 4.10.0.20 now but I got one with 4.10.0.19. I ran 4.11 RC8 for a week and did not get the freeze. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1677491 Title: System freeze Status in linux package in Ubuntu: Confirmed Bug description: I'm getting a system freeze, consisting of all applications slowing down and stopping to respond. This starts happening after some hours of normal functioning of the system. A reboot recovers the system until the next freeze. It doesn't seem that any application is exhausting the memory.
