Issue

At the time Hitachi submitted its certification request for BladeSymphony(Hitachi Compute Blade) 2000 including hardware partitioning (also known as Virtage in Japan), as the system can be configured with kdump, when we didn't use the "nmi_watchdog=0" parameter, the kdump failed frequently.

Resolution

  • The problem can be worked around by adding the boot option "nmi_watchdog=0" to /etc/grub.conf

  • Here's example for x86_64:

title Red Hat Enterprise Linux (2.6.32-131.0.15.el6.x86_64)
     root (hd0,0)
     kernel /vmlinuz-2.6.32-131.0.15.el6.x86_64 root=/dev/mapper/VolGroup-lv_root ro rd_LVM_LV=VolGroup/lv_root rd_LVM_LV=VolGroup/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us nomodeset crashkernel=256M@48M rhgb quiet nmi_watchdog=0
     initrd /initramfs-2.6.32-131.0.15.el6.x86_64.img
  • Also example for i686
title Red Hat Enterprise Linux (2.6.32-131.0.15.el6.i686)
     root (hd0,0)
     kernel /vmlinuz-2.6.32-131.0.15.el6.i686 root=/dev/mapper/VolGroup-lv_root ro rd_LVM_LV=VolGroup/lv_root rd_LVM_LV=VolGroup/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us nomodeset crashkernel=256M@48M rhgb quiet nmi_watchdog=0
     initrd /initramfs-2.6.32-131.0.15.el6.i686.img
