nothing related to OpenBSD, but some problem with my system. I get this: $ nproc 28 $ cat /sys/devices/system/cpu/offline 4-7 $ cat /sys/devices/system/cpu/online 0-3,8-31 $
so 1 core = 4 threads are offline. I'll dig further into it. thanks, Ed Sent with Proton Mail secure email. ------- Original Message ------- On Wednesday, April 19th, 2023 at 2:42 AM, George Koehler <kern...@gmail.com> wrote: > On Sat, 15 Apr 2023 09:30:00 +0000 > Eduardo Pires eduardo.pi...@protonmail.com wrote: > > > Hi George, > > > > does any of those errors tell you something? > > > > ... > > cpu1: 10MB 128b/line 8-way L3 cache[ 126.324667899,3] OPAL: CPU not active > > in OPAL ! > > failed to start, error -14 > > ... > > opal0: idle psscr 300332 > > [ 126.331347066,3] OPAL: CPU not active in OPAL ! > > opal0: failed to idle pir 13, error -14 > > [ 126.331405980,3] OPAL: CPU not active in OPAL ! > > opal0: failed to idle pir 14, error -14 > > [ 126.331460755,3] OPAL: CPU not active in OPAL ! > > opal0: failed to idle pir 15, error -14 > > ... > > > Error -14 is OPAL_WRONG_STATE > http://open-power.github.io/skiboot/doc/opal-api/return-codes.html?highlight=opal > error#opal-wrong-state > > pir c, d, e, f = 12, 13, 14, 15 looks like all 4 threads of a core, > so something is wrong with that core.
