Here is what worked and what did not and what I ended up using: reboot=a * SUCCESS reboot=b * FAIL reboot=cold * FAIL reboot=efi * FAIL reboot=force * FAIL reboot=h * FAIL reboot=p * SUCCESS reboot=s * FAIL reboot=t * SUCCESS reboot=warm * FAIL I am using reboot=a for now, until INTEL releases a BIOS fix for this bug. >From Bryan: Try each of the following in the reboot= parameter: acpi, smp (32-bit only), triple, efi, pci, warm, cold, force If one of them works, report it, along with the output from dmidecode and lspci -nn, so a workaround entry can be added. dmidecode & lspci below-- http://home.comcast.net/~jpiszcz/20091015/dmidecode.txt http://home.comcast.net/~jpiszcz/20091015/lspci-nn.txt Justin. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
