"devices=0x30000" means that two ATAPI devices were detected instead of one. I can reproduce it also with other Intel chipsets. It looks like a hardware bug to me. It can be workarounded by reconnecting ATAPI device to even (2 or 4) SATA port, or connecting any other device there. 2. "DISCONNECT requested" means that controller reported PHY status change for some device on channel, triggering infinite retry. Unluckily I have no ICH9 board, while I can't reproduce it with ICH10 or above. This patch should workaround the first problem in software: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/chipsets/ata-intel.c.diff?r1=1.25;r2=1.26 Try it please and let's see if with some luck it do something about the second problem. -- Alexander Motin
