Eitan, I've attached the patch - this came from David Naylor on the ACPI list. If I understand what he told me at the time, it doesn't fix the problem entirely - but I can't pretend I understand ACPI. I know it means that on my S10e I no longer get spammed with ACPI errors - and that my battery status and shutdown work properly. The patch applies to /usr/src/sys/dev/acpica/acpi_ec.c It needs some new entries in /boot/loader.conf to adjust the timeouts and delays - which you can tinker with. The settings given are what works for me - but search the acpi list archives for David's original email: debug.acpi.ec.delay="200" debug.acpi.ec.gpe="1" debug.acpi.ec.timeout="100" Hope it helps, Peter Harrison. > > > > > > > ... > > I see > > ACPI Exception: AE_NO_HARDWARE_RESPONSE, Returned by Handler for > > [EmbeddedControl] (20100331/evregion-588) > > ACPI Error (psparse-0633): Method parse/execution failed > > [\\_SB_.PCI0.LPCB.BAT1._BST] (Node 0xc6adba60), > > AE_NO_HARDWARE_RESPONSE > > > > repeatedly in dmesg > > > > sysctl's relating to battery information is also slow: > > % time sysctl hw.acpi.battery.state > > hw.acpi.battery.state: 7 > > sysctl hw.acpi.battery.state 0.00s user 2.18s system 72% cpu 3.006 total > > > > % time sysctl hw.acpi.battery > > hw.acpi.battery.life: -1 > > hw.acpi.battery.time: -1 > > hw.acpi.battery.state: 7 > > hw.acpi.battery.units: 1 > > hw.acpi.battery.info_expire: 5 > > sysctl hw.acpi.battery 0.00s user 6.58s system 67% cpu 9.779 total > > > > also note that the life and time are both negative one. > > > > This is on a Lenovo G530 laptop. > -- > Eitan Adler _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
