I've = finally settled on a RedHat 7.2 distribution and the 2.4.24 kernel. All worked = well with the MTD drivers in several other setups: RedHat 9, Mandrake 9.2, = but for reasons I can't yet fathom, the MTD drivers seem a bit unstable in = this particular kernel. Most frequently when I perform a umount /mnt/doc (doc being the mount = point) the shell session freezes (the umount command does not return a prompt). If I then perform a sfdisk -l /dev/nftla the command again goes off into space with no return data. Then the shut down hangs up. I tried in one kernel build to apply the latest sources to my source = tree using the instructions (and the shell script) but this caused a compile failure. =20 May I have some suggestions as to how I can further diagnose this = problem, or what I can do to provide information that will help? Many thanks, Mark
