There was one bug which has been haunting kernels since 2.6.37 (as reports
indicated) which can cause bad dereferences under high(er) load. The related
bug number would be bug #854050. A patch was found and got somewhat stuck on
its way upstream.
So the fix only went into our tree quite late and was not included in any
kernel updates until now. The patch would be:
commit cc1f777ce7526f1fdc25cdf7b99ea75adc9764ce

UBUNTU: SAUCE: x86/paravirt: Partially revert "remove lazy mode in
interrupts"
[The upstream commit will have a different commit message, though]
