On a A21m, I've loaded acpi_ibm after boot, and now psm0 appears to be dead. vmstat -i reports a total of 73 interrupts for irq12, and it doesn't increase when I push one of the buttons, or move the stick. Interestingly enough, after rebooting and loading acpi_ibm from loader.conf, everything seems to be working just fine. Stefan -- Stefan Bethke <stb@lassitu.de> Fon +49 170 346 0140
