Description NIKA 2013-01-05 00:40:00 UTC

I get a bug when I run install program FreeBSD 9.1 on my ASUS A7U notebook (ATI RS690 chipset; ATI SB600 south bridge; Seagate SATAI harddrive; BIOS a7uas.206, if it's important). This bug I have posted already (it has ID "kern/174880"), but later I guessed to turn on Verbose option and wrote detailed dmesg. So, previous PR is about the same bug and can be closed.

The bug is the following. FreeBSD 9.1 (FreeBSD 8.3 too) can not see my harddrive. The message is: "ahcich1: Timeout on slot 0 port 0". So, install program can not resume - no hard drive in the system. My BIOS does not have option to switch drive to PATA mode, so AHCI is required.

At the same time, FreeBSD 7.4 can see it. With FreeBSD 7.4 is no problem. Clearly, some bug in AHCI or ATA-ATI driver appeared in 8R.

I am interested to use PCBSD, but can not do it. Please, help.

Below - messages from dmesg, which can relate to this bug (FreeBSD 9.1):

dmesg message got lost somewhere. Unfortunately I haven't seen the
problem on hardware I have, so try to give more information.

PS: Please boot with verbose messages enabled in boot menu to get more
