Could you cc the list when you do alert (I assume) the acpi list (if

Ubuntu Hardy) prior to 2.6.25 release.
That's doubtful. Let's see what Len wants to do with this...
But as soon as there is a patch or a decision of some sort, I will post to
the lists.
I looked in drivers/acpi/osl.c ... and noticed in
dmi_system_id_acpi_osl_dmi_table(), 2 matches that they use. Though I
am unsure about a prober match for this. The issues you have is the
laptop is vendor LENOVO and the Version ThinkPad T61. But obviously
not all LENOVO laptops will not use this (or will they?) .. and your
going to want to have a Version that is more then T61. I assume most
if not all future Lenovo laptops will be following this standard.
I'd just whitelist all with vendor LENOVO and Version ThinkPad*. But that's
my opinion, and I doubt Len (the ACPI maintainer) would agree (and he *does*
have good reasons not to). For now, it is best if users simply add the
acpi_osi parameter.
On the contrary, when i add acpi_osi=Linux kernel parameter, the mute
button been disabled.
After remove the acpi_osi parameter, mute button works again.
My laptop: thinkpad X61 7675 ThinkPad BIOS 7NET30WW (1.11 ), EC
7MHT24WW-1.02
2.6.24-rc7 ThinkPad ACPI Extras v0.19-20080107
