Hi, on my Notebook ( Thinkpad T43) I can not boot with V3.4-rc1. The kernel stops booting after displaying the following: ACPI: Core revision 20120320 ACPI: setting ELCR to 0200 (from 0800) Performance Events: p6 PMU driver. ... version: 0 ... bit width: 32 ... generic registers: 2 ... value mask: 00000000ffffffff ... max period: 000000007fffffff ... fixed-purpose events: 0 ... event mask: 0000000000000003 devtmpfs: initialized NET: Registered protocol family 16 ACPI: bus type pci registered PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0xe0000000-0xefffffff] (base 0xe0000000) PCI: MMCONFIG at [mem 0xe0000000-0xefffffff] reserved in E820 PCI: Using MMCONFIG for extended config space PCI: Using configuration type 1 for base access bio: create slab <bio-0> at 0 ACPI: Added _OSI(Module Device) ACPI: Added _OSI(Processor Device) ACPI: Added _OSI(3.0 _SCP Extensions) ACPI: Added _OSI(Processor Aggregator Device) ACPI: EC: EC description table is found, configuring boot EC Comparing this with the displays of kernel v3.3 the next expected outputs would be: ACPI: Interpreter enabled ACPI: (supports S0 S5) Regards, Joerg Otte -- 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
