ACPI freeze the kernel while booting

[pidanc_j <pidanc_j@xxxxxxxx>]

When enabling ACPI in my laptop, the kernel froze after displaying this:

[...]
acpi0: <INSYDE RSDT_000> [tentative] on motherboard
AcpiOsDerivePciId: bus 2 dev 0 func 0
AcpiOsDerivePciId: bus 2 dev 2 func 0
AcpiOsDerivePciId: bus 2 dev 6 func 0
AcpiOsDerivePciId: bus 0 dev 31 func 0
AcpiOsDerivePciId: bus 0 dev 31 func 0
AcpiOsDerivePciId: bus 0 dev 31 func 0

My laptop is a Compal CL-56.
ACPI works fine with FreeBSD. dmesg :
[...]
npx0: [FAST]
npx0: <math processor> on motherboard

p4tcc0: <CPU Frequency Thermal Control> on cpu0
acpi_lid0: <Control Method Lid Switch> on acpi0

[..]

I didn't notice problems with acpi disabled in dragonflyBSD.

Thx for help.
