    Description

      Hello,

      One of our, DDN Japan, customer faced kernel panic with RIP in "RIP [<ffffffffa07a32e3>] ll_readahead+0x43/0x1d20 [lustre]".
      Attached is the console log of this client.

      Could you check if this is Kernel/BIOS issue or Lustre issue?

      Many thanks,
      Minoru@DDN Japan

            Agreeded. If they face same panic without hardware error, I'll open this again.
            So please close this.
            Many thanks.

            I'd say it's mostly like a hardware problem in this case (memory failure).

            We can see followings in /var/log/messages before that panic happened.
            MEMLOG[44377]: r001i23b07 P0D-DIMM1A has a failed DRAM and must be replaced soon. Exposure to Uncorrected Error is high

            the log.txt relates to Lustre and the fat_panic_log does not, does the system has memory issue?

            Hi Bojijam,

            They couldn't get any kernel dump this time..
            Could you check whether the root cause of the panic is related to lustre or not with only console msg?

            Many thanks,
            Minoru
