Subject: Boot problem on PPC with 4.4-git - Bisected to commit 21266be
Date: Wed, 20 Jan 2016 14:01:45 -0600 [thread overview]
Message-ID: <569FE7A9.7090902@lwfinger.net> (raw)
My PowerBook G4 Aluminum with a 32-bit PPC processor fails to boot for the
4.4-git series. The problem was bisected to commit 21266be. It took a while to
figure out why a commit that only rearranges the Kconfig files could cause the
problem.
The answer came when I read the commit message for 90a545e98126 and saw that
"Recompiling with CONFIG_IO_STRICT_DEVMEM=n" might be necessary. After I made
that change, the system boots.
If it is the graphics hardware driver at fault, the VGA controller is listed as
an ATI RV350 [Mobility Radeon 9600 M10] with PCI ID 1002:4350. It uses radeon as
the driver.
I'm not sure if this is a bug in the configuration, but I know that selecting
the default answer to all the new configuration parameters leaves me with a
machine that is unbootable.
