With 2.6.23-rc1 however the APM driver fails to locate the APM bios: --- dmesg-2.6.22 2007-07-23 14:07:46.000000000 +0200 +++ dmesg-2.6.23-rc1 2007-07-23 14:48:24.000000000 +0200 @@ -102,7 +105,7 @@ Unpacking initramfs... done Freeing initrd memory: 976k freed Machine check exception polling timer started. -apm: BIOS version 1.2 Flags 0x07 (Driver version 1.16ac) +apm: BIOS not found. io scheduler noop registered io scheduler anticipatory registered (default) io scheduler deadline registered The only change in 2.6.23-rc1 to arch/i386/kernel/apm.c is a trivial nofreeze flag removal, so I suspect the boot code changes, perhaps the new arch/i386/boot/apm.c:query_apm_bios(). /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
