RHEL 2.1 is no longer receiving routine bug fix updates. Only security and
critical issues are being addressed. Since there is a workaround for this issue,
it does not qualify. Also, Red Hat recommends the use of parted instead of fdisk.
Users who have experienced this problem are encouraged to upgrade to the latest
update release, and if this issue is reproducible with parted, please contact
the Red Hat Global Support Services page on our website for technical support
