Then it gets further down the road than my N160 with 5.0R...

Subject: ACPI locks up during boot on Compaq EVO N10
To: [email protected]

Hi,
     
I could use some expert advice on the following.
I recently loaded 5.0-RELEASE on my Compaq EVO N160 laptop.

Given that this is a newish laptop which really depends on
ACPI FreeBSD 5 is the way to go. 4.7-stable runs fine on it,
but lacks all power management etc.

Unfortunately during boot the machine locks up with a couple
of ACPI messages. This happens just after the "Mounting root"
message.

ACPI says:

ACPI-0331: Connot release mutex [MUT0], not acquired
ACPI-1287: error: method execution failed, AE_AML_MUTEX_NOT_ACQUIRED

Hmm, I got panics then, but I don't remember when I tried it exactly.
