Subject: [PATCH] platform/x86: thinkpad_acpi: disable bluetooth for some
machines
[EXTERNAL EMAIL]
Some AMD based ThinkPads have a firmware bug that calling
"GBDC" will cause bluetooth on Intel wireless cards blocked.
Hi,
Thanks for your suggestions.
Since this is considered a firmware bug; has the OEM (and IBV) been notified?
Is it
fixed in a newer version of the firmware?
No. I've noticed them about the bug but they said these models have no
official Linux support so no plan to fix.
If so, then this should probably only match particular broken firmware versions.
Disable bluetooth subdriver on these models should be safe since Intel
cards have built-in RFKill and there is no bluetooth hotkey on these
machines.
Probe these models by DMI match and disable bluetooth subdriver
if specified Intel wireless card exist.
