I've performed an experiment with the same switch and sil 3135. I used a linux x86 pc w/ kernel 2.6.24 -- Everything worked and was detected correctly. I placed the switch into a 16 lane port. So this confirms that the electronics on the switch and sata controller are correct. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ U-Boot-Users mailing list U-Boot-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/u-boot-users
