Hi all: Whenever I shutdown a domU, I always get the same soft lockup panic ( I copied itat the bottom of this email), and most of the times I have to completely reboot my machine. I have been trying to debug this error, and it seems that the CPUs where the soft lockup is detected, are effectively being shut down (should the soft lockup detector being run on those CPUs that are being shutdown?). However, in one of the cases, the CPU in soft lockup is executing force_evtchn_callback Any ideas? Running unstable on RHEL, 32procs (physical, ht off), 64 GB RAM, Thanks, Pablo BUG: soft lockup detected on CPU#30!
