In my case it froze everytime "wlp4s0: WPA: Group rekeying completed with ..." appeared in the logs or if I manually connected to the wifi.
Disabled ipv6, didn't crash so often anymore and not on each manual connect anymore. But still had some freezes (especially if the CPU load changed abruptly), until I switched to the 147 kernel. In logs I saw the kernel page error and also that the CPU throttled shortly before the crashes. Not sure if this helps to pinpoint the exact cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938013 Title: 4.15.0-151 is freezing various CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
