Thanks for your answer. The problem is still there, unfortunately. Crashes no more on pagedaemon though, for a change, but on irq48:em0... Would you have KVA_PAGES / maxvnodes recommendation for this case ? Was your answer based on painful trial-and-error, or is there a logical=20= reason (known bad HTT or PAE or Xeon support) ? Should I revert to 4-STABLE to get solid PAE+SMP support ? -- Emmanuel OTTON - Ecole des Mines d'Albi-Carmaux - Responsable=20 informatique T=E9l: 05 63 49 30 86
