Evgeny's (eumaster) and Uli's chipsets are both: north-bridge: nvidia c51mv south-bridge: nvidia mcp51m Also both are MSI laptops: - MSI-M670, modell MS-1632 - MSI S430x (This could also be a chipset or even an MSI specific BIOS bug? Richard could you compare with your HW, pls if still possible). Some more info: - things break entering C2 or deeper - noapictimer workaround helps to come a bit further, but results in sever other errors, disk(dma error), keyboad, mouse etc., also see: https://bugzilla.novell.com/show_bug.cgi?id=396220#c13 - "nohz=off" works (tested on 2.6.25.4-8-pae and 2.6.22.17-0.1-default SUSE kernels) - processor.max_cstate=1 works Thomas lspci 00:00.0 RAM memory: nVidia Corporation C51 Host Bridge (rev a2) 00:00.1 RAM memory: nVidia Corporation C51 Memory Controller 0 (rev a2) 00:00.2 RAM memory: nVidia Corporation C51 Memory Controller 1 (rev a2) 00:00.3 RAM memory: nVidia Corporation C51 Memory Controller 5 (rev a2) 00:00.4 RAM memory: nVidia Corporation C51 Memory Controller 4 (rev a2) 00:00.5 RAM memory: nVidia Corporation C51 Host Bridge (rev a2) 00:00.6 RAM memory: nVidia Corporation C51 Memory Controller 3 (rev a2) 00:00.7 RAM memory: nVidia Corporation C51 Memory Controller 2 (rev a2) 00:03.0 PCI bridge: nVidia Corporation C51 PCI Express Bridge (rev a1) 00:05.0 VGA compatible controller: nVidia Corporation MCP51 PCI-X GeForce Go 6100 (rev a2) 00:09.0 RAM memory: nVidia Corporation MCP51 Host Bridge (rev a2) 00:0a.0 ISA bridge: nVidia Corporation MCP51 LPC Bridge (rev a3) 00:0a.1 SMBus: nVidia Corporation MCP51 SMBus (rev a3) 00:0a.3 Co-processor: nVidia Corporation MCP51 PMU (rev a3) 00:0b.0 USB Controller: nVidia Corporation MCP51 USB Controller (rev a3) 00:0b.1 USB Controller: nVidia Corporation MCP51 USB Controller (rev a3) 00:0d.0 IDE interface: nVidia Corporation MCP51 IDE (rev a1) 00:0e.0 IDE interface: nVidia Corporation MCP51 Serial ATA Controller (rev a1) 00:10.0 PCI bridge: nVidia Corporation MCP51 PCI Bridge (rev a2) 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) 00:14.0 Bridge: nVidia Corporation MCP51 Ethernet Controller (rev a3) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
