Mandrake has released updated kernels. You find the upgrade information
below.

Upgrade procedure
-----------------
 It is recommended that you download the necessary RPMs and upgrade
 manually by following these steps:

  - first download all the necessary RPMs for your platform
  - type: rpm -ivh kernel-2.2.19-4.1mdk.i586.rpm
  - type: mv kernel-2.2.19-4.1mdk.i586.rpm /tmp
  - type: rpm -Fvh *.rpm
  - type: mkinitrd -f --ifneeded /boot/initrd-2.2.19-4.1mdk 2.2.19-4.1mdk
  - type: ln -sf /boot/initrd-2.2.19-4.1mdk /boot/initrd.img
  - edit /etc/lilo.conf and double-check the options
  - type: /sbin/lilo -v

 Replace the kernel revision noted in the above instructions with those
 from the packages you downloaded.   You will then be able to reboot and
 use the new kernel and remove the older kernel when you are comfortable
 using the upgraded one.
