Hi!
Recently I tried to figure out in 2.5.65, why throughput on my disk which
hangs on Silicon Image 680 dropped to 1/4 compared to 2.4.21-pre5, but didn't
found anything useful. Are there any known issues with this driver?
Comparing those two drivers - they are exactly the same. Cabling is OK
(with 80w cable), the driver correctly detects this (checked with this simple
patch:
