Would you be able to check whether you can reproduce this on the vanilla 2.6 sources? Thanks! Failed against vanilla sources. Submitted upstream. http://bugme.osdl.org/show_bug.cgi?id=2153 Created attachment 26005 [details]

2.6.3-vanilla/ksymoops
Changed to UPSTREAM - will reopen/give more details from the upstream devs as they become available. The following patched fixed the problem. This has been applied to the 2.6.4 kernel.
