Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi ! I run FreeBSD ( 2.2 BETA and 2.2R) on the one computer about 4 months and never seen any system crashes, except the msdosfs bugs, system console locks if I try to mount bad msdos media ( diskette/hdd) . Few days ago I try to move filesystems code from kernel to LKMs- such as NFS, CD9660, MSDOSFS. It works good, but I for first time in my expirience with FreeBSD on this machine see actually seriuos system crash: Fatal trap 12: page fault while in kernel mode, supervisor read, page not present Fault virtual address = 0xuglyc0de Kernel dumped at swap device 1 . I see thats when I try to mount not very good WORM-CD ( recorded 680MB, can see only about of 400MB). I see crashes of FreeBSD only on broken motherboards. We had 5x86 motherboard with broken RAM subsystem. Kernel regularly paniced with message " Double Fault ". Any suggestions ? Thanks , Vasily . ******[FreeBSD it is coolest UNIX for PC!]******* * System admin , ftp and web master. * * Home Page: http://www.econ.acnit.ac.ru/ * * E-mail: bazilio@economic.acnit.ac.ru * * * * Industrial Economy Departament * * Voronezh State Technical University * *************************************************
