ata problems on SiS 962/963 controller

[Gordon Bergling]

Hi folks,

I discovered a little problem with the ata controller of my new
notebook. This notebook has a 40 GB ATA-6 capable hdd. FreeBSDs ATA
driver recognized this only as a UDMA-33 drive. The appropriate dmesg
lines are:

| atapci0: <SiS 962/963 UDMA133 controller> port
| 0xffa0-0xffaf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 2.5 on pci0
|
| ata0-master: DMA limited to UDMA33, non-ATA66 cable or device
|
| ad0: 38154MB <FUJITSU MHT2040AT/0022> [77520/16/63] at ata0-master
| UDMA33

Another problem is that sometimes the dvdr drives gets not recognized
and after a few seconds the system panics. That happend only two times
and I haven't had the change to get a core dump yet.

I had tried the boot without acpi, but it changed nothing. The second
panic was without acpi. The wrong ata mode is also used without acpi.
The dmesg and the verbose dmesg output can be found at

Any hints to solve this? If I could provide further information, please
let me now.

best regards,

	Gordon
