April 2, 20188 yr Hello Running 6.4.1. I was looking at something else, but noticed something weird. In lscpu my CPU shows as 1 thread per core, 1 core per socket. But it's a quad core CPU, correctly identified below in the model name. Any thoughts what could be going on? uname -a: Linux hoth 4.14.16-unRAID #1 SMP PREEMPT Wed Jan 31 08:51:39 PST 2018 x86_64 AMD Ryzen 5 1500X Quad-Core Processor AuthenticAMD GNU/Linux root@tower:/# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 1 On-line CPU(s) list: 0 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 1 NUMA node(s): 1 Vendor ID: AuthenticAMD CPU family: 23 Model: 1 Model name: AMD Ryzen 5 1500X Quad-Core Processor Stepping: 1 CPU MHz: 3765.126 BogoMIPS: 6985.71 Virtualization: AMD-V L1d cache: 32K L1i cache: 64K L2 cache: 512K L3 cache: 8192K NUMA node0 CPU(s): 0 Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc cpuid extd_apicid aperfmperf pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw skinit wdt tce topoext perfctr_core perfctr_nb bpext perfctr_llc mwaitx cpb hw_pstate sme retpoline retpoline_amd vmmcall fsgsbase bmi1 avx2 smep bmi2 rdseed adx smap clflushopt sha_ni xsaveopt xsavec xgetbv1 xsaves clzero irperf xsaveerptr arat npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold avic v_vmsave_vmload vgif overflow_recov succor smca hoth-diagnostics-20180402-1954.zip syslog.txt Edited April 9, 20188 yr by misteral Whoops
April 3, 20188 yr Author 1 hour ago, unevent said: Post a diagnostics file. Whoops, thanks. Added to the main thread
April 3, 20188 yr Noticed "acpi=off' was added to the boot command line options. That was a workaround for early 2017 Ryzen BIOS/kernel issues and I believe in 4.11+ kernels, especially 4.14 that your on now it should not be necessary and is most likely the reason only one core is being detected/used. If I am incorrect someone will most likely say so. Suggest removing that option from the boot command and reboot then post a new diagnostics.
April 8, 20188 yr Author Thanks for this! I removed it and cleaned up some other pieces (some old packages were loading in /boot packages). New log attached hoth-diagnostics-20180408-1738.zip syslog.txt
April 9, 20188 yr That looks as though it fixed it: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 2 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: AuthenticAMD CPU family: 23 Model: 1 Model name: AMD Ryzen 5 1500X Quad-Core Processor Are you happy now?
