Description Richard W.M. Jones 2010-07-23 14:54:08 UTC

Description of problem:

From upstream bug report:

> DMI string system-manufacturer: "# SMBIOS implementations newer than version 2.6 are not"
> DMI string system-product-name: "# SMBIOS implementations newer than version 2.6 are not"
> DMI string system-version: "# SMBIOS implementations newer than version 2.6 are not"
> DMI string baseboard-manufacturer: "# SMBIOS implementations newer than version 2.6 are not"
> DMI string baseboard-product-name: "# SMBIOS implementations newer than version 2.6 are not"
> DMI string baseboard-version: "# SMBIOS implementations newer than version 2.6 are not"
> DMI string chassis-type: "# SMBIOS implementations newer than version 2.6 are not"
>   

Now this is a serious problem. Apparently dmidecode in Fedora has a
patch in the RPM (dmidecode-warn-on-unsupported-smbios-version.patch)
which breaks the original documented output format. If this only
affected the board enables, it wouldn't be that bad (failing/corrupting
writes on a few dozen boards which can be fixed interactively), but it
also completely disables laptop detection and that means Fedora will get
bug reports about hard lockups and/or disabled fans on laptops.
I don't want to blame Fedora because this is a patch hand-picked from
upstream dmidecode. We'll add a workaorund to flashrom ASAP.

Anton's taking care of dmidecode these days, not I.
