Gigabyte GA-EX58-UD5 PC doesn't power off

[Bruce Cran]

Hi,

I've just installed -CURRENT onto a new PC based on the Gigabyte GA-EX58-UD5 
motherboard and found that it doesn't power off.  Instead it displays:

Uptime: 3m5s
unknown: wake_prep disabled for \_SB_.PCI0.IGBE (S5)
uhci3: wake_prep disabled wake for \_SB_.PCI0.USB0 (S5)
uhci4: wake_prep disabled wake for \_SB_.PCI0.USB1 (S5)
uhci5: wake_prep disabled wake for \_SB_.PCI0.USB2 (S5)
uhci0: wake_prep disabled wake for \_SB_.PCI0.USB3 (S5)
uhci1: wake_prep disabled wake for \_SB_.PCI0.USB4 (S5)
uhci2: wake_prep disabled wake for \_SB_.PCI0.USB5 (S5)
ehci1: wake_prep disabled wake for \_SB_.PCI0.USBE (S5)
ehci0: wake_prep disabled wake for \_SB_.PCI0.USB2 (S5)
acpi0: Powering system off

I've put a verbose dmesg at 
http://www.cran.org.uk/~brucec/freebsd/dmesg_20100301.verbose and the ACPI 
tables at http://www.cran.org.uk/~brucec/freebsd/ga_ex58_ud5.asl .

While running acpidump I noticed the warning "acpidump: RSDT entry 4 (sig 
TAMG) is corrupt".
