Patch fixing the issue
Our partners product a Java Virtual Machine, does not run on RH EL 3 (64-bit) on the EM64T platform. This is important for us to have a 32- bit JVM run on the 64-bit OS on our EM64T enabled platforms. It runs without changes on the RHEL 4 (beta) on EM64T. Sample testcase was representative of what the virtual machine uses. Geoff Gustafson posted the patch in comment #3 on 11/10 for consideration in U5. A fix for this problem has just been committed to the RHEL3 U5 patch pool this evening (in kernel version 2.4.21-27.7.EL). An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2005-294.html |
