Is there any help IBM can offer with this BZ?
Comment 6 Konrad Rzeszutek 2006-12-13 17:02:11 EST
Asking for exception. The justication is that the steps to reproduce this
are quite simple: "
--Steps to Reproduce---
1. launch a RHEL guest and auto-attach console (xm create guest -c)
2. On the Grub menu, hit 'e' to edit the boot entry
3. Hit 'e' a second time to edit that line
4. Use the right arrow key to move the cursor past the last character in the line
5. hit backspace"

and that a customer could hit this while playing with Xen.
