I have 3112 Silicon Image controller with IDE drive attahed. (I have 2 IDE drives, so I bought second controller to split load between them. One is connected to the MB IDE controller.) When I run hdparm command, I can see strange behaviour of the ilbata driver: [root@shrike root]# hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 64 MB in 1.19 seconds = 53.78 MB/sec [root@shrike root]# hdparm -t /dev/sda1 /dev/sda1: Timing buffered disk reads: read(1048576) returned 921600 bytes [root@shrike root]# Meanwhile -T switch works normally. I know, that siimage support is broken, any ideas, what can possibly cause such errors? Is it somehow linked to the error discussed in this message thread?
