ACPI Exception AE_NO_MEMORY

[Jukka Marin <jmarin%muikku.jmp.fi@localhost>]

Dear Lists,

Last night, my Xen / i386PAE (netbsd-5) server had died with "ACPI
Exception" messages flooding on console.  The full messge was:

ACPI Exception (evgpe-0886): AE_NO_MEMORY, Unable to queue handler for
 GPE[ 8] - event disabled [20080321]

Is there something I can do to prevent this from occurring again?

Thanks.
