Setting MC_MISC_CNTL.GART_INDEX_REG_EN causes hangs on some boards on resume. The systems seem to work fine without touching this bit so leave it as is. v2: read-modify-write the GART_INDEX_REG_EN bit. I suspect the problem is that we are losing the other settings in the register. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=52952 Reported-by: Ondrej Zary <linux@rainbow-software.org> Tested-by: Daniel Tobias <dan.g.tob@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org |
