@Kai-Heng In answer to your question "Can you confirm v4.11 freezes but v4.12-rc1 doesn't?", I can confirm that 4.11.12 freezes. Kernel log shows "NMI watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [kworker/3:1:70]".
Below are the test details along with the corresponding kernel log output. Kernel version used during this test: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11.12/ linux-headers-4.11.12-041112_4.11.12-041112.201707210350_all.deb linux-headers-4.11.12-041112-generic_4.11.12-041112.201707210350_amd64.deb linux-image-4.11.12-041112-generic_4.11.12-041112.201707210350_amd64.deb Detailed answer: v4.11.12 -> default kernel settings -> Progress icon rotates endlessly. When toggling to the ttl output I see "NMI watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [kworker/3:1:70]" and many more. -> See attached file kernel.log.4.11.12.WithDefaultKernelArguments.log v4.11.12 -> NOMODESET -> Progress icon was displayed and rotated for a while but then the entire computer turned off. -> Not frozen but dead. -> See attached file kernel.log.4.11.12.nomodeset.log v4.11.12 -> "blacklist=nouveau modprobe.blacklist=nouveau" -> I could login without problems and the desktop appears to be displayed and working as I would expect. -> See attached file kernel.log.4.11.12.blacklist.nouveau.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697556 Title: Computer freezes after login - 4.10.0-22-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1697556/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
