    SR2612UR server reboots with CATERR

    Florin

      Hello,

       

      I have a SR2612UR server with S5520UR board and RS2bl040 raid controller. I have recentrly installed some Samsung SSD's and the performance was improved but after a few days the server rebooted unexpectedly. In Intel Active System Console i found the following logs:

      I found on some other forums that C6 State setting from BIOS could cause some troubles and disabling could solve those random reboots. Coult that be the sollution? Is there any side effects for disabling C6 CPU State?

          I would suggest you first check if your BIOS/Firmware is updated. Also check if the components, especially memory, is on the Tested memory and hardware list.

           

          As for C-states, those are the power saving states to reduce power consumption while the CPU is idle. Deeper C-States means lower power consumption, but longer entry/exit latency. C6 is the deep power down state that the CPU internal voltage is close to 0. You may try to disable it as a step of troubleshooting.

            The memory rdimms are KVR13R9D4/8I and are on the tested list but the SSDs are not on that list. We will try first to disable C6 state from bios and hope it will solve our problem. We will schedule a downtime for this operation and come back with updates.

            Thanks
