I have three systems of which two show this problem. Two systems are ASUS "All-in-One PC ET2230I". One is an ACER All-in- One PC Aspire C24-760.
All were installed from Ubuntu 16.04.1 and have been updated to the latest patch sets as of 2018/04/14. The ASUS systems do not boot with 4.13.0-38. The hang is the same as above with the last thing showing that the kernel was loading the RAM disk. The ACER system boots fine with the -38 kernel. The two kernels I tried on these systems are: (Working on ASUS) Linux domiclient2.domistyle.ad 4.13.0-31-generic #34~16.04.1-Ubuntu SMP Fri Jan 19 17:11:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux (Working on ACER, but failing on ASUS) Linux domiclient1.domistyle.ad 4.13.0-38-generic #43~16.04.1-Ubuntu SMP Wed Mar 14 17:48:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux I manually selected the -31 kernel and the two ASUS systems boot correctly. No obvious problems. When I either manually interrupt GRUB and select the -38 kernel or I allow GRUB to select it, the ASUS systems hang. The non-working ASUS systems have older CPUs: root@domiclient2:~# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 60 model name : Intel(R) Core(TM) i3-4150T CPU @ 3.00GHz stepping : 3 microcode : 0x22 cpu MHz : 2993.244 cache size : 3072 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm cpuid_fault epb invpcid_single pti tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid xsaveopt dtherm arat pln pts bugs : cpu_meltdown spectre_v1 spectre_v2 bogomips : 5986.48 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: The ACER system has a newer CPU: cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 78 model name : Intel(R) Core(TM) i3-6100U CPU @ 2.30GHz stepping : 3 microcode : 0x84 cpu MHz : 800.011 cache size : 3072 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 22 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc art arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf tsc_known_freq pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch cpuid_fault epb invpcid_single pti retpoline intel_pt rsb_ctxsw tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 hle avx2 smep bmi2 erms invpcid rtm mpx rdseed adx smap clflushopt xsaveopt xsavec xgetbv1 xsaves dtherm ida arat pln pts hwp hwp_notify hwp_act_window hwp_epp bugs : cpu_meltdown spectre_v1 spectre_v2 bogomips : 4608.00 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1751584 Title: Ubuntu doesn't boot with 4.13.0 kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1751584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
