While running tests on foundation and fast models. stage2_unmap_vm() triggers the softlockup watchdog (on a reboot). I have not tried to reproduce on hardware or work with the thresholds (watchdog_thresh()) these could be more aggressive and usually are in more critical environments. I think that calling 'touch_softlockup_watchdog()' someplace while walking second stage tables should prevent this. On hardware huge VMs may be susceptible to this. This is only likely to happen when main memory is fragmented and 2nd stage tables are backed by pages. With huge pages only everything appears to work fine. - Mario _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
