Description
   A doing a successfull installation from DVD and the system reboots, the bootloader gets activated but hangs very soon afterwards.
If I change the boot parameters either in grub/menu.lst or interactively during the boot process so it'll boot in 32 bit mode everything works as expected.
If I change the memory to 2*1 Gb everything I can boot into 64bit without any post install changes.
I assume that this bug is very closely related ahci driver doesn't work for ATI SB600 AHCI chipset (ASUS M2A-VM)
Frequency
   Always
Regression
   No
Steps to Reproduce
   Using the afore mentioned hardware do a clean installation of snv_94 from dvd. This will succeed. A disks get recognized since the installer runs in 32 bit mode. Please note that I installed the root on the PATA/IDE disk NOT on a sata.
Expected Result
   I expected the system to boot into 64bit mode.
Actual Result
   After the succesfull installation the system will reboot. The grub menu appears, the default option (the plain opensolaris boot) will timeout and the os gets loaded. But it hangs, the disk activity led remains illuminated.

Workaround
   Change the boot parameters either in grub/menu.lst or interactively during the boot process so it'll boot in 32 bit mode.
Remove memory so much memory that there is less than 4GB installed. Although I only tested it with 2*1GB memory.

Additional configuration information
   An ASUS M3A H/HDMI motherboard with bios 0605
A BE2400 processor
An pata/ide root disk
Between 4 and 6 sata disks
An intel pro1000 pciE nic
2*2Gb Kingston ECC pc5300 (667MHz)
most important in the bios the disk controller mode is set to AHCI mode

N/A

ATI SB700 AHCI chipset (1002,4391) doesn't support 64-bit dma address although the HBA's register declares it supports, so the ahci driver should force it to use 32-bit dma addressing.
