Re: BUG: soft lockup - CPU#6 stuck for 61s! [apache2:18704]
FWIW I am seeing soft lockups under high VM<->VM network communication as well, using XenServer 5.6FP1 with the hotfix applied that supposedly fixes this.. the kernel version is: 2.6.32.12-0.7.1.xs5.6.100.316.170595xen Not sure if this has been sufficiently resolved in later Xen versions or not.
