Response from AMD: http://marc.theaimsgroup.com/?l=linux-kernel&m=114548768214478&w=2 A fix for this problem has just been committed to the RHEL3 U8 patch pool this evening (in kernel version 2.4.21-40.9.EL). The patch introduced a bug in FP exception handling: http://marc.theaimsgroup.com/?l=linux-kernel&m=114633448824132&w=2 Thanks, Marcel. As it turns out, the patch committed to RHEL3 uses a "C" statement to perform the test, and the compiler generated the correct code. Thus, no regression was caused in RHEL3. 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-2006-0437.html |
