https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234676 --- Comment #8 from johan van Zanten <johanvz816@giantfoo.org> --- Per the ACPI debugging docs: https://docs.freebsd.org/doc/5.5-RELEASE/usr/share/doc/handbook/acpi-debug.= html I tried adding this to loader.conf: hint.apic.0.disabled=3D"1"=20 ...and the system panics with 12.0 as well as 11.2 kernels. (The latter bo= ots without that line in loader.conf.) The traceback from the panic in the 12.0 kernel (i think it was the same in 11.2): cryptosoft0: <software crypto> on motherboard acpi0: <060410 RSDT1553> on motherboard acpi0: could not allocate interrupt ACPI Error: AE_ALREADY_EXISTS, Unable to install System Control Interrupt handler (20181003/evevent-260) acpi0: Could not enable ACPI: AE_ALREADY_EXISTS device_attach: acpi0 attach returned 6 panic: No usable event timer found! cpuid =3D 0 time =3D 1 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff82665= b30 vpanic() at vpanic+0x1a3/frame 0xffffffff82665b90 panic() at panic+0x43/frame 0xffffffff82665bf0 cpu_initclocks_bsp() at cpu_initclocks_bsp+0x3dd/frame 0xffffffff82665c20 cpu_initclocks() at cpu_initclocks+0x15/frame 0xffffffff82665c40 initclocks() at initclocks+0x20/frame 0xffffffff82665c50 mi_startup() at mi_startup+0x118/frame 0xffffffff82665c70 btext() at btext+0x2c KDB: enter: panic [ thread pid 0 tid 100000 ] Stopped at kdb_enter+0x3b: movq $0,kdb_why --=20 You are receiving this mail because: You are on the CC list for the bug.=
