Then I managed to get Nan hai's original patch against 2.6.19.. http://marc.info/?l=linux-ia64&m=116521104831321&w=2 This patch doesn't have zero-vmcore problem. Given the age of the kdump feature and so many upstream releases since 2.6.20, I'm in doubt why I don't see this kind of bug report on ia64 mailing list before? PS. Now I can start to capture info for the strace problem with 2.6.19 kernel +Nahai's 2.6.19 kdump patch, hope the problem is still reproducible.
