Message-ID: User-Agent: Alpine 2.00 (DEB 1167 2008-08-23) MIME-Version: 1.0 Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2142 Lines: 58 Hi, I have tried the following kernel parameters with '*' and reboot=b, reboot=h and reboot=s. ----------------------------------------------------------------------- Rebooting reboot=b[ios] | t[riple] | k[bd] | a[cpi] | e[fi] [, [w]arm | [c]old] * bios Use the CPU reboot vector for warm reset warm Don't set the cold reboot flag cold Set the cold reboot flag triple Force a triple fault (init) * kbd Use the keyboard controller. cold reset (default) acpi Use the ACPI RESET_REG in the FADT. If ACPI is not configured or the ACPI reset does not work, the reboot path attempts the reset using the keyboard controller. * efi Use efi reset_system runtime service. If EFI is not configured or the EFI reset does not work, the reboot path attempts the reset using the keyboard controller. Using warm reset will be much faster especially on big memory systems because the BIOS will not go through the memory check. Disadvantage is that not all hardware will be completely reinitialized on reboot so there may be boot problems on some systems. * reboot=force None of which work. ----------------------------------------------------------------------- It appears earlier Intel boards also suffered the same problem: Subject: Re: Machine restart doesn't work - Intel 965G, 2.6.19-rc2 http://lkml.indiana.edu/hypermail/linux/kernel/0610.2/2215.html Are those at Intel aware of this problem? I have tried many different options/settings, nothing seems to work. All workaround are unsuccessful. It appears the dmidecode is requested for these sorts of problems, that is available here: http://home.comcast.net/~jpiszcz/20091014/dmidecode.txt Are there any other workarounds until Intel comes out with a patch/new BIOS? Aside from shutting the system off and using wake on lan?
