Workaround: Congure virtual drives using the SAS conguration utility. To access the SAS
conguration utility, enter Control-C when prompted during the BIOS boot sequence.
x86: ata Timeouts During Boot (6586621)
ata driver timeouts might occur during system boot on Intel multiprocessor systems. These
timeouts occur when the root device is on a drive with the HBA controller bound to the legacy
ata driver. These timeouts lead to a momentary hang, hard hang, or a panic during system boot
with console messages similar to the following:

Workaround: Choose one of the following workarounds:
Note – To avoid performance degradation, workaround 3 or workaround 4 should only be used
temporarily until workaround 5 can be used .
■
Workaround 1: Enable AHCI in BIOS if available on the system. Enabling this setting
requires a reinstall of the Solaris OS.
■
Workaround 2: Install Solaris on a disk on a controller which does not use the ata driver.
■
Workaround 3: Disable MP in the BIOS setup so that a single processor is active.
■
Workaround 4: Disable MP in Solaris so that a single processor is active. Perform the
following steps from the Grand Unied Bootloader (GRUB) menu:
