x86: ASUS P4S800 reboot=bios quirk
Bug reporter noted their system with an ASUS P4S800 motherboard would hang when rebooting unless reboot=b was specified. Their dmidecode didn't contain descriptive System Information for Manufacturer or Product Name, so I used their Base Board Information to create a reboot quirk patch. The bug reporter confirmed this patch resolves the reboot hang. Handle 0x0001, DMI type 1, 25 bytes System Information Manufacturer: System Manufacturer Product Name: System Name Version: System Version Serial Number: SYS-1234567890 UUID: E0BFCD8B-7948-D911-A953-E486B4EEB67F Wake-up Type: Power Switch Handle 0x0002, DMI type 2, 8 bytes Base Board Information Manufacturer: ASUSTeK Computer INC.
