Checked out using the following tags:
-r RELENG_4 -D "2002/09/14 00:00 UTC"
>Description:
The ATA controller in the SiS951 chipset is not recognized properly. This causes FreeBSD to treat it as a basic ATA controller. However using the default BIOS config (with ultra-dma enabled) this causes the system to freeze as soon as the system tries to use the hard drives.
While this controller supposedly supports ATA-133, using it like other ATA-100 chipsets from SiS fixes the problem.
>How-To-Repeat:
>Fix:
Either disable 'ultra-dma' from the bios or add code to detect the SiS951 integrated ATA controller in the same way as the SiS950 chipset.
The parent device ID for this chipset is: 0x06511039
The following patch does the trick:
