Apparently, there is more code trying to call pmap_remove() early, mostly to free preloaded memory. Instead of moving all deallocations to the point where a scheduler is initialized, add missed setup of thread0 di init at hammer_time(). The code in pmap_delayed_invl_start_u() is modified to not ever take the thread lock if the thread priority is less or equal to PVM. Since thread0 starts at priority 0, and then is reset to PVM at proc0_init(), this eliminates taking the thread lock during early boot. While there, fix off by one in comparision of the base priority. Reported and tested by: bcran (previous version) Reviewed by: markj Sponsored by: The FreeBSD Foundation MFC after: 29 days

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
