Now I have a second SMP machine (Fujitsu Siemens TX200 with two Xeon) with same configuration, now FreeBSD 4.8-STABLE. "Same procedure than last year Mrs. Sophie ?" "Same procedure than every year James !". With an uptime of about 2 days I got today the first crash: stack trace is: (kgdb) where #0 0xc016e052 in dumpsys () #1 0xc016de23 in boot () #2 0xc016e27c in poweroff_wait () #3 0xc02286ca in vm_page_free_toq () #4 0xc02274bc in vm_object_collapse () #5 0xc02266d0 in vm_object_deallocate () #6 0xc0223b74 in vm_map_entry_delete () #7 0xc0223d2d in vm_map_delete () #8 0xc0223dba in vm_map_remove () Someone has an idea other than turn off SMP ?
