Dear guys, i've some problems with ACPI in FreeBSD and my HP 2133 Mininote. Basically, when i try to query the ACPI about the laptop's temperature i get this: piso@nanobook:~ >sysctl -a | grep temp net.inet6.ip6.use_tempaddr: 0 net.inet6.ip6.temppltime: 86400 net.inet6.ip6.tempvltime: 604800 net.inet6.ip6.prefer_tempaddr: 0 hw.acpi.thermal.tz0.temperature: 58.0C ^C^C^C^C^C^C^C^C^C^C^C <---- here the console is stuck ACPI Exception (exutils-0382): AE_TIME, Could not acquire Global Lock [20070320] ACPI Exception (exutils-0382): AE_TIME, Could not acquire Global Lock [20070320] Moreover after a bit of usage my laptop become so hot that it's impossible to hold. Here is the a dmesg snippet about an ACPI error i get at boot time: ACPI Error (exmutex-0479): Cannot release Mutex [_GL_], not acquired [20070320] ACPI Error (psparse-0626): Method parse/execution failed [\\_SB_.PCI0.SBRG.SMAB] (Node 0xc48f2800), AE_AML_MUTEX_NOT_ACQUIRED ACPI Error (psparse-0626): Method parse/execution failed [\\_SB_.PCI0.ACEL.AJAL] (Node 0xc48e8560), AE_AML_MUTEX_NOT_ACQUIRED ACPI Error (psparse-0626): Method parse/execution failed [\\_SB_.PCI0.AC0_._PSR] (Node 0xc48f04c0), AE_AML_MUTEX_NOT_ACQUIRED For full verbose dmesg see here: http://people.freebsd.org/~piso/hp2133-dmesg-verbose.txt and for more info about my laptop see here: http://gentoo-wiki.com/HARDWARE_HP_2133_Mini-Note_PC -- bye, P.
