Sorry, my last response went t othe wrong list.

I also see this weird message on a ASUS CUR-DLS based SMP system with 
two PIII/1GHz CPUs. Very often, when
SMP is active (with or without ACPI), typing 'systat -vmstat 1' I get 
the above mentioned error message. In very, very
rare cases this occurs also under UP conditions, but in nearly 50% of 
all cases under SMP conditions. As I said, either with
or without ACPI enabled.
In the past I reported about a strange behaviour of FreeBSD 5.3 (I 
utilize FreeBSD 5.3-STABLE on this box). SMP is not working. I was told 
this is possibly due a hardware error.
