Escalated to Bugzilla from IssueTracker
I fixed a similar issue on RHEL4 (Bug 160230) and backported the fix to RHEL3 (Bug 142579). The crash log attached to this report shows the same symptom: a crash in a code path that uses phys_to_nid(). The faulting address (0x18f0) is also exactly the same as seen in the other bugs. I'm closing this as a dup of 142579. A fix for the latter has been proposed for U7. *** This bug has been marked as a duplicate of 142579 ***
A fix for this problem has just been committed to the RHEL3 U7 patch pool this evening (in kernel version 2.4.21-37.3.EL). Propagating acks from bug 142579.
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.
