I also noticed that the cause of the problem is pretty surely Xmarks. So, if I remove ~/.mozilla firefox3 works again. When I reinstall Xmarks the system freezes. Attilio Rao (rookie), an italian kernel developer suggest me to recompile the kernel using the options, KDB, DDB, GDB, KDB_UNATTENDED (in particular the last one, that reboot the machine if a panic occurs), but I didn't obtain nothin' useful, because isn't a panic (the machine doesn't reboot) neither dmesg is more verbose about the problem. I also tried to recompile firefox from ports w/ DEBUG flag enable, but I don't see anythin' good launching firefox from xterm. Regards Davide
