The default location is /var/crash. Look for files named vmcore.N, where N is a number. What kind of USB chip do you have on the motherboard? Try 'dmesg | grep ^usb' and post the output. > My computer is either hanging up for ever, I can't move mouse or use > keyboard anymore, juste reset, or hang up a few seconds and reboot by > it self. It could be a hardware problem, or a bug. Does anything appear in the dmesg output when you try to plug in a USB device? look in /var/log/messages, at the correct time. E.g, the following appears when I plug in a USB flash drive; Apr 22 18:24:45 slackbox kernel: umass0: <vendor 0x3538 USB Mass Storage Device, class 0/0, rev 2.00/1.00, addr 2> on uhub4 Apr 22 18:24:45 slackbox kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Apr 22 18:24:45 slackbox kernel: da0: <Generic USB Flash Disk 0.00> Removable Direct Access SCSI-2 device Apr 22 18:24:45 slackbox kernel: da0: 40.000MB/s transfers Apr 22 18:24:45 slackbox kernel: da0: 250MB (512000 512 byte sectors: 64H 32S/T 250C) Seeing which of these lines appear or not makes it easier to track down the bug. Try to read the crashdump with the kernel debugger, as described in §10.2 of the FreeBSD Developers' Handbook. Obtain a so-called backtrace. (using the 'bt' command in the debugger). Post your question and the information that you've gathered to the -stable mailing list. There are more people there who are familiar with the kernel internals.
