I'm getting about three of each at boot. I'm running: commit e1cca7e8d484390169777b423a7fe46c7021fec1 Date: Thu Nov 29 16:25:29 2007 -0800 which is the latest git as of yesterday plus a one (unrelated) debug statement patch in usb uhci. There was a similar bug report after 2.6.23-rc8-mm was released. Though there seems to be a fundamental problem with how people use smp_call_function*() [1]. And this can just as well be another incarnation of it. Is that easy enough to fix or do I need to bisect (it didn't happen in 2.6.24-rc3)? tom [1] http://kerneltrap.org/mailarchive/linux-kernel/2007/9/27/324310
