Subject: Work around Dell E520 BIOS reboot bug
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b9e82af823c10d8f981072e0d7c3a8a31f73e0bd;p=openwrt%2Fstaging%2Fblogic.git

Work around Dell E520 BIOS reboot bug

Force Dell E520 to use the BIOS to shutdown/reboot.

I have at least one report that this patch fixes shutdown/reboot
problems on the Dell E520 platform.

(Andi says: People can always set the boot option.  It hardly seems like a
critical issue needing a backport.)
