Ian,
Sorry for the delay. The development box in question has older hardware, so it
takes a long time to compile a kernel to investigate various possibilities.
We were running an earlier version of the 2.6.32.25 pvops kernel, on Xen 4.0.1.
Apparently the fault is caused by the -j switch in make, but not always. I can
compile the newer kernel single-threaded without any problems (other than I
have to run it overnight), without ever reproducing the problem, so it cannot
be in kernel source or the tools per se. We have been running (and building
Xen) on the newer snapshot xen-3d14ce7 kernel with no problems.
Debugging this problem uncovered a different issue with the IBM sHype security
features (ACM), so we are focused on that for now.
I will start logging more, whenever I build a new pvops kernel, to see if I can
collect anything useful. We will also have a look at adding a kernel build to
our development stress tests.
Sincerely,
John
