2.6.23-rc5 hangs on boot, apparently when initializing the EC

2.6.23-rc5-git1 hangs here, just before EC initialization. Pressing the power button briefly makes it continue, then the EC gets detected twice:

ACPI: bus type pci registered
PCI: Using configuration type 1

------------------ hangs here, press power button --------------------

ACPI: EC: Look up EC in DSDT
ACPI: EC: GPE = 0x10, I/O: command/status = 0x66, data = 0x62
ACPI: System BIOS is requesting _OSI(Linux)
ACPI: If "acpi_osi=Linux" works better,
Please send dmidecode to [email protected]
ACPI: Interpreter enabled
ACPI: (supports S0 S3)
ACPI: Using IOAPIC for interrupt routing
ACPI: EC: GPE = 0x10, I/O: command/status = 0x66, data = 0x62
ACPI: PCI Root Bridge [PCI0] (0000:00)
PCI: Transparent bridge - 0000:00:10.0
...

System is an HP TX1000 notebook with AMD Turion X2 processor, running the x86_64 kernel. (And acpi_osi="Linux" doesn't seem to make any difference.)

Chuck,

Please try last patch from bug 8709 (bugzilla.kernel.org), if it does not help, please open new bug, and submit acpidump and dmesg outputs.

Thanks,
Alex.
