Hello, all.

I have not worked acpi on Acer Travel Mate 4151LMi with FreeBSD 6.0
Beta 5.
Laptop driven i915 with shared video and ich6 sata.
If i compile 'device acpi' into kernel after detect hdd/dvd i got this
messages: ad2: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=139842480
ad2 - its hdd.
If i set in loader.conf 'hw.ata.ata_dma=0' i got
ad2: TIMEOUT - READ_MUL retrying (1 retry left) LBA=.........
Next i playing with 'debug.acpi.disabled=' in loader.conf
System just hang up/not found hdd.
After this i dumped asl, found 3 warning, commented out strings with
warning and configured in loader.conf
acpi_dsdt_load=yes+acpi_dsdt_name=DSDT.aml (compiled w/o warnings).
System just rebooting during boot process.
Next i disabled 'device apic' in kernel, results the same.
Above test do with _disabled_ PREEMTION, WITHNESS.

W/o acpi all worked fine, except suspend, battery indicator, etc.
Any ideas or i should write PR?
