Kernel iswraid module (Intel software raid for ICH5-R/ICH6 chipsets) is too old in Sisyphus. It has 0.0.6 version of this module. It causes segmentation fault when I try to load it. I recompile kernel with latest 0.1.4 version of this module and it works fine.
Was fixed in kernel-image-std-*-2.4.27-alt1.
Verified.
