Hi, yesterday I recompiled the kernel on my late 2005 G4 PowerBook, and the Wifi stopped working. After comparing the configuration is turns out that a change to a Kconfig condition disabled SSB support which is necessary for these chips. The graph of configuration options is quite messy, and I'm not sure that I fully understand it. Nevertheless the following patch fixes the regression, but there might be a better way to solve the problem. If you pick up this trivial patch as is, you may add: Signed-off-by: Gabriel Paubert <redacted>diff --git a/drivers/ssb/Kconfig b/drivers/ssb/Kconfig index 71c7376..d189db6 100644 --- a/drivers/ssb/Kconfig +++ b/drivers/ssb/Kconfig@@ -32,7 +32,7 @@ config SSB_BLOCKIO config SSB_PCIHOST_POSSIBLE bool - depends on SSB && (PCI = y || PCI = SSB) && PCI_DRIVERS_LEGACY + depends on SSB && (PCI = y || PCI = SSB) && (PCI_DRIVERS_LEGACY || B43_SSB) default y config SSB_PCIHOST
Yes, really sorry about that. There is a patch here: https://patchwork.kernel.org/patch/10185397/ which is applied to linux-next as commit a9e6d44ddeccd3522670e641f1ed9b068e746ff7. Cheers James
