• Nvidia Linux Card not working due to LSI 9200/SAS2008 IRQ conflict


    At first my BIOS said the card may not work right because there is no more option ROM space. I disabled the Option ROM for both LSI 1068 and 2008 chipsets, Network Boot ROM and most other PCI slots, Serial Port, etc... and the message went away but the card still does not work properly. But it still cannot initialize the card properly(does not work): [ 33.943272] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:........

    I am getting this error: kernel:[14277.697049] EDAC MC0: UE row 4, channel-a= 0 channel-b= 1 labels "-": (Branch=0 DRAM-Bank=0 RDWR=Read RAS=7048 CAS=0 FATAL Err=0x4 (>Tmid Thermal event with intelligent throttling disabled)) But many people believe this is a bug/false message and the server is running stably.........

    I'm not sure why I'm getting these but all memory modules are the exact same and all passed memtest successfully although they are ECC. I've heard that ECC RAM can't be tested as well and the kernel seems to indicate they are non-fatl recoverable errors. I wonder if the BIOS has aggressive RAM timing or maybe the controller or motherboard is bad. [ 12.716515] EDAC MC: Ver: 2.1.0 [ 12.717771] EDAC MC0: Giving out device to........

  • LSI MegaRAID Adventures, Guide and HowTo


    LSi Megaraid At first it was configured as a RAID 0, then I deleted the Virtual Disk Group. I thought both drives would be shown and detected in Linux as sda and sdb but it actually shows nothing. To make them work you have to hit Ctrl+R before the system boots (when prompted) and create a Virtual Disk Group. In my case I created each one as RAID 0 (with a single drive only) as I just wanted JBOD but there is no such option or default in these Dell Pe........
