Also, please report how adding "hw.acpi.ec.burst_mode=0" to loader.conf
changes things (but turn on hw.acpi.verbose first so we get good msgs).
Well with hw.acpi.verbose=1 the messages look like this:

here is the output of "dmesg | egrep acpi_ec0\|EC\ Wait"

I set hw.acpi.ec.burst_mode=0 in loader.conf but when i was trying to 
chek if it was set to 0 with sysctl hw.acpi.ec.burst_mode i got :

[EMAIL PROTECTED] [~] 15 #sysctl hw.acpi.ec.burst_mode
sysctl: unknown oid 'hw.acpi.ec.burst_mode'
Let me know if i can do something else.
