Hello there! Unfortunately I've server, that requires to manually point kernel to RSDP- table. Otherwise ACPI doesn't work properly and kernel limits processors to 1. All the time until upgrade to 3.12.5/3.12.6 I did it by specifying acpi_rsdp=0x7F1F7000 to the kernel cmdline (where 0x7F1F7000 is real address of RSDP table) and all worked fine. But now, after the upgrade, kernel can't find RSDP table anyway, even with redefinition in cmdline, and so it prints > [ 0.000000] ACPI BIOS Error (bug): A valid RSDP was not found (20130725/tbxfroot-212) And boots just like I don't specified real RSDT table address for it (with 1 processor and with broken acpi functionality). As far, as I investigated, probleam appeared after http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=40031da445fb4d269af9c7c445b2adf674f171e7 Unfortunately, I can't fully bisect it and get exact place. Can you advice me, if it is possible to redefine RSDP table now, in 3.12, and how? And if it should use same syntax — why it stop working? -- Best regsrds, mva -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
