commit 163ea310b68bdde89b1ac633fbf8c0db290d3f86 Author: Ben Date: Sat May 3 22:39:42 2008 +0200 x86: remove dell reboot dmi quirk board name match http://bugzilla.kernel.org/show_bug.cgi?id=10547 Newer Dell OptiPlex 745s hang before rebooting after 'sudo reboot'. A patch for some versions of the OptiPlex was proposed here -- http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and later kernels, according to http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However, the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex machines have a DMI_BOARD_NAME of "0RF703". I therefore suggest adding another clause to reboot.c, similar to the one in the original patch, but matching a DMI_BOARD_NAME of "0RF703". On further inspection, it seems that there are other DMI_BOARD_NAMEs for this same machine. They seem to change from time to time, which means that the current code is fragile. Moreover, using bios reboot should not break non-SFF OptiPlex 745s, and so a reasonable fix is to simply drop the match on DMI_BOARD_NAME.
