Hi, after upgrading to 2.6.32.2, with the attached config, kernel booting always(just tried 10+ times) failed at: ata1.00: SATA link down (SStatus 0 SControl 301) ... VFS: Cannot open root device ... ver_linux info: /usr/src/linux/scripts/ver_linux If some fields are empty or look unusual you may have an old version. Compare to the current minimal requirements in Documentation/Changes.

Thanks. PS. When using 2.6.32-rc8 and 2.6.32,the same problem happened twice, but i can't reproduce that.
