Comment # 4 on bug 56878 from miri@turboprinzessin.de

If I read dmesg correctly, it defaults to agp mode 2 but the bug still appears
with radeon.agpmode=1. Using radeon.agpmode=-1 avoids the freeze, though.
agpmode=-1 will be slower than the default, won't it? Anything else I can do to
help with fixing this bug?
