I had several Dell Optiplex 9020, 7040 and 7050, all with a Nvidia GeForce 1050 Ti, that froze while booting Ubuntu 16.04 with Kernel 4.13.0-31.34~16.04.1. Kernel 4.13.0-26.29~16.04.2 works fine.
On some PCs that I booted without the quiet option in GRUB_CMDLINE_LINUX_DEFAULT the last message on the screen was the start of the System Security Services Daemon and of Postfix, respectively. After that the PCs froze and didn't even respond to ping. On one PC I got the error messages NMI watchdog: Watchdog detected hard LOCKUP on cpu 0 NMI watchdog: Watchdog detected hard LOCKUP on cpu 2 NMI watchdog: Watchdog detected hard LOCKUP on cpu 3 INFO: rcu_sched detected stalls on CPUs/tasks: #0-...: (1 GPs behind) idle=456/14000000000001/0 softirq=27381/2 #3-...: (1 GPs behind) idle=d1a/14000000000000/0 softirq=29304/2 #(detected by 1, t=15002 jillies, f=061, c=860, q=1378) rcu_sched kthread starved for 15000 jiffies! g861 c860 f0x0 I haven't yet seen this boot problem of kernel 4.13.0-31 on other Dell PCs with onboard graphics. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1744942 Title: Lenovo IdeaPad U460 fails to boot with 4.13.0-31.34~16.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1744942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
