I am getting Fatal trap 12: page fault while in kernel mode when booting GENERIC debug kernel with ACPI disabled on Supermicro X7SB4 motherboard with dual core Xeon CPU. instruction pointer = 0x20:0xc0a49aea [root@cad ~]# nm -n /boot/kernel/kernel|grep c0a49ae c0a49ae0 T ioapic_get_vector Booting custom kernel shows up the same routine. Here is dmesg after boot -v: http://pastebin.ca/936377 [root@cad ~]# sysctl hw.acpi hw.acpi.supported_sleep_state: S1 S4 S5 hw.acpi.power_button_state: S5 hw.acpi.sleep_button_state: S1 hw.acpi.lid_switch_state: NONE hw.acpi.standby_state: S1 hw.acpi.suspend_state: S3 hw.acpi.sleep_delay: 1 hw.acpi.s4bios: 0 hw.acpi.verbose: 1 hw.acpi.disable_on_reboot: 0 hw.acpi.handle_reboot: 0 hw.acpi.reset_video: 0 hw.acpi.cpu.cx_lowest: C1 acpidump -dt is located at: http://www.lecad.uni-lj.si/~leon/tmp/supermicro-x7sb4.asl Supermicro X7SB4 motherboard with latest BIOS Boot GENERIC with ACPI disabled FreeBSD cad.lecad.uni-lj.si 7.0-STABLE FreeBSD 7.0-STABLE #0: Mon Mar 10 10:26:30 CET 2008 root@cad.lecad.uni-lj.si:/usr/src/sys/i386/compile/GENERIC i386 Booting with ACPI does not show this problem. Another ACPI problem with this board: Normal boot with ACPI enabled does not handle reboot. It locks up after shutdown and does not reboot. Last syslog lines are: Mar 10 08:21:51 cad rc.shutdown: 30 second watchdog timeout expired. Shutdown terminated. Mar 10 08:21:51 cad init: /bin/sh on /etc/rc.shutdown terminated abnormally, going to single user mode Mar 10 08:21:51 cad syslogd: exiting on signal 15 Settin hw.acpi.disable_on_reboot and hw.acpi.handle_reboot does not help. Under FreeBSD 6.3 the same system rebooted normaly. Kind regards. Leon Kos, CAD lab, Mech.Eng., University of Ljubljana, Slovenia (http://www.lecad.uni-lj.si/~leon)
