Subject: [PATCH] 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.
