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: diff -urN -X dontdiff linux-2.5.65/drivers/ide/pci/siimage.c linux-2.5.65-sii/drivers/ide/pci/siimage.c --- linux-2.5.65/drivers/ide/pci/siimage.c 2003-02-25 21:30:39.000000000 +0100 +++ linux-2.5.65-sii/drivers/ide/pci/siimage.c 2003-03-23 21:36:37.000000000 +0100 @@ -90,8 +90,11 @@ break;
