Hi ! I grabbed the newest -current and enabled Softtupdates. I don't know, if this problem is more related to softupdates, SMP or to -current's vm system. I already noticed, that some people seemed to have trouble with enabling noatime. This is the first panic, but I'll keep you informed. It happened when I left X11 session with CTRL-ALT-BS Here what DDB told me: Fatal trap 12: page fault while in kernel mode mp_lock=00000002 cpuip=0 lapic.id=01000000 fault virtual address = 0xf1349ff8 Supervisor read page not present ...
