Hi. Nathan Ahlstrom has been helping me try to gather up information to solve a problem with FreeBSD-Stable and asked me to send the following information to freebsd-hackers. The problem is that Freebsd-Stable crashes after just a few hours of use. No core file is generated either. The crashing occurs on two separate machines, one a dual-p133 and the other a 486-33. Both these kernels are only hours old. I have been updating the kernels daily in hopes of a fix. If any further information is needed, please let me know.
