I have just taken the system on a Sony Vaio PCG-Z505SX laptop from 6.1-RC1 (2006/03/23) to 6.1-STABLE (2006/05/09) using a cvsup update and full buildworld/buildkernel rebuild, while keeping the same kernel config. On booting the new system, apm no longer works. Now, acpi never work on this hardware anyway, but apm always worked fine. On the 6.1-STABLE kernel, it doesn't probe or load properly at boot time. For reasons I no longer recall, "device apm" is configured in this kernel, rather than loading it as a module, and this has been fine for years, in fact, since back in the 5.x days and for several 6.0 kernels as well as 6.1-RC1. Here's the pertinent boot info: FreeBSD 6.1-RC1 (2006/03/23): real memory = 134152192 (127 MB) avail memory = 121733120 (116 MB) ACPI disabled by blacklist. Contact your BIOS vendor. npx0: [FAST] npx0: <math processor> on motherboard npx0: INT 16 interface cpu0 on motherboard apm0: <APM BIOS> on motherboard apm0: found APM BIOS v1.2, connected at v1.2 pcib0: <Intel 82443BX host to PCI bridge (AGP disabled)> pcibus 0 on motherboard pir0: <PCI Interrupt Routing Table: 7 Entries> on motherboard FreeBSD 6.1-STABLE (2006/05/09): real memory = 134152192 (127 MB) avail memory = 121733120 (116 MB) ACPI disabled by blacklist. Contact your BIOS vendor. cpu0 on motherboard apm: Other PM system enabled. pcib0: <Intel 82443BX host to PCI bridge (AGP disabled)> pcibus 0 on motherboard pir0: <PCI Interrupt Routing Table: 7 Entries> on motherboard On 6.1-STABLE, the /dev/apm device is not created and so none of the apm tools work. I don't see any changes to any of the apm code (in the last year or so, actually), so this is presumably due to a change at a lower level? Any thoughts? -jr
