Hello, I have got again the 100% CPU for nash during today's kernel update with yum. The system gets to the following state: - nash takes 100% CPU - 2 processes of mkinitrd are running - initrd for the new kernel is created - grub.conf is not updated Then I kill the nash (kill 7634) and the yum's update continues without any related error and also the grub.conf is updated. The last kernel I had installed was 2.6.17-1.2396 and the new was 2.6.17-1.2405. SELinux policy packages were updated during the same transaction, but before the kernel update.
