 I recently hit a problem with linux 2.6.32 kernel which might
 be related to the present problem with freebsd boot.
 At times the system became unresponsive for a short period
 of time and the message: 
 ata1.00: exception Emask 0x0 SAct ...
 appeared in dmesg.
 The solution was to put pci=noacpi in the boot options.
 Any similar option on FreeBSD disabling only part of acpi?
