The problem is that arch/i386/kernel/microcode.o is listed in linux-modules-unsupported-hugemem. I'm not sure why this is, but it looks like we should remove it. I'll investigate this. A fix for this problem has just been committed to the RHEL3 U6 patch pool this evening (in kernel version 2.4.21-32.7.EL). *** Bug 132754 has been marked as a duplicate of this bug. *** 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.
