Description of problem: Unless *all* registers are restored to pre-PXE status, localboot doesn't work. We are clobbering DS, ESI and EDX when chainloading an NBP, which means that localboot won't work in the chainloaded NBP. Version-Release number of selected component (if applicable): syslinux-3.11-4 How reproducible: Always on specific IBM machines: x3850 M2 (7141) x3650 (7979)(only those with E5405 Quad-core CPUs) HS21 (8853) (only those with E5405 Quad-core CPUs). Steps to Reproduce: 1. PXE boot one of the mentioned servers. 2. Select localboot option. 3. Actual results: The network boot sequence starts over again. Expected results: The system boots from localdisk.

This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release.
Further investigation has revealed we cannot fix this issue without an entire rebase of syslinux in RHEL-5. Doing so at this point is too risky for a problem that has a documented workaround: http://www-947.ibm.com/support/entry/portal/docdisplay?brand=5000008&lndocid=MIGR-5084755 The problem has been fixed upstream, so RHEL-6 and later should not exhibit this problem.
Development Management has reviewed and declined this request. You may appeal this decision by reopening this request.
