Greetings, Following the list this pasts days as a sysadmin, building a big machine with 45 sata2 disks (WD green 1.5TB), Sil3124 4 ports sata2 with 9 port multipliers with 5 each also from Silicom image. This machine should smoke but it doesn't, attached is the dmesg dump Using Ubuntu/server 10.4 2.6.32-25-server x86_64 using sata_sil24 disks and bios controlers supports Western Digital Green drivers or any other kind of disks, sort of bug or simply a sysctl value. will provide more logs if needed, 2.6.36-rc3 ? thanks ./hantunes
