--- Comment #8 from johan van Zanten <johanvz...@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="1" ...and the system panics with 12.0 as well as 11.2 kernels. (The latter boots 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 = 0 time = 1 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff82665b30 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 -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-acpi@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscr...@freebsd.org"
