First of all disabling USB didn't change anything. I then suped RELENG_5 to several dates in between March 17 and April 17 and found that the problem appeared after Mar-31-05:00 and before Mar-31-11:00. cvsup between these two timestamps shows two changes: Edit src/release/doc/en_US.ISO8859-1/relnotes/common/new.sgml Add delta 1.761.2.38 2005.03.31.06.28.58 hrs Edit src/sys/dev/acpica/acpivar.h Add delta 1.79.2.7 2005.03.31.06.03.59 njl and diffing acpivar.h reveals: _at__at_ -25,7 +25,7 _at__at_ * OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF * SUCH DAMAGE. * - * $FreeBSD: src/sys/dev/acpica/acpivar.h,v 1.79.2.6 2005/03/02 09:18:41 obrien Exp $ + * $FreeBSD: src/sys/dev/acpica/acpivar.h,v 1.79.2.7 2005/03/31 06:03:59 njl Exp $ */ #ifndef _ACPIVAR_H_ _at__at_ -406,7 +406,7 _at__at_ ACPI_HANDLE acpi_GetReference(ACPI_HANDLE scope, ACPI_OBJECT *obj); #ifndef ACPI_MAX_THREADS -#define ACPI_MAX_THREADS 3 +#define ACPI_MAX_THREADS 1 #endif /* ACPI task kernel thread initialization. */ I suped back to 5-STABLE and changed ACPI_MAX_THREADS accordingly and the problem has now disappeared: # sysctl hw.acpi.battery hw.acpi.battery.life: 87 hw.acpi.battery.time: 167 hw.acpi.battery.state: 1 hw.acpi.battery.units: 1 hw.acpi.battery.info_expire: 5 # uname -a FreeBSD 5.4-STABLE FreeBSD 5.4-STABLE #7: Wed Apr 20 00:49:58 CEST 2005 root_at_6nq.u-strasbg.fr:/usr/obj/usr/src/sys/GENERIC i386 BTW -CURRENT has the same problem (MFC from 1.91) and the same change fixes it. gbReceived on Wed Apr 20 2005 - 05:04:32 UTC
