Seems like low priority to me (correct me if I'm wrong). Postpone to next release
Comment 3 Glauber Costa 2009-07-15 20:27:58 EDT
moving to component etherboot, which is the guilty one in here.

However, It will probably never have a fix in etherboot, because etherboot community reaction seems to be "etherboot is deprecated, use gpxe instead".

So what we shoul really focus on, is in having gpxe working with this test case,
and fix it otherwise.
Comment 4 Miya Chen 2009-07-27 07:15:30 EDT
this problem still exists when using gpxe.

Glauber, why do you think it's etherboot? It does not work from gPxe either and the bios code should run the ide.
Comment 6 Glauber Costa 2009-09-29 07:54:52 EDT
I had debugged a similar problem in the past, and came to the conclusion that it happened because etherboot rewrote int19 handler, but then did not restore it when we gave up booting from network. It would mean that booting from local is then impossible.

Note that it might be possible that gpxe has the same problem. The main advantage of gpxe is that it is not deprecated, and we can fix it.
Comment 13 RHEL Product and Program Management 2011-01-11 15:47:44 EST
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
Comment 14 RHEL Product and Program Management 2011-01-11 17:32:34 EST
This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.
