Oh....sorry, but I met next panic attack :(


After updating src-all, re-patching  and recompiling I am left with acpi 
errors during boot and panic. I tried all patches you send (ecng7a/b/c). 


battery0: <ACPI Control Method Battery> on acpi0
acpi_ec0: EcRead: failed waiting to get data
ACPI Exception (evregion-0529): AE_NO_HARDWARE_RESPONSE, Returned by Handler 
for [EmbeddedControl] [20070320]
ACPI Error (psparse-0626): Method parse/execution failed 
[\_SB_.PCI0.LPC0.EC0_.BAT0._STA] (Node 0xffffff00011610a0), 
AE_NO_HARDWARE_RESPONSE
ACPI Error (uteval-0309): Method execution failed 
[\_SB_.PCI0.LPC0.EC0_.BAT0._STA] (Node 0xffffff00011610a0), 
AE_NO_HARDWARE_RESPONSE
acpi_acad0: <AC Adapter> on acpi0




AND if I unplug the power cable system panics.
Piece from core dump:

panic: _sx_xlock_hard: recursed on non-recursive sx ACPI embedded controller 
@ /usr/src/sys/dev/acpica/acpi_ec.c:209

KDB: enter: panic
panic: from debugger
Uptime: 5m55s
Physical memory: 884 MB
Dumping 56 MB:



System also panics if I try to boot without power cable plugged..
