Hi, This mailing list is my last resort for a hideous problem I've endured for well over a year. I first started experiencing it with FreeBSD 4.2-R. I bought the FreeBSD 4.3-R CDs when they first came out last year, hoping that the problem would disappear. It didn't. I have searched through the freebsd.org problem reports and mailing list arhives, through USENET, and through google.com. Although it seems many other users are experiencing similar problems, solutions have been elusive. [problem description] The system locks up very often. While using X, it appears that the system freezes completely with the keyboard and mouse becoming unresponsive, but this is not the case -- after a brief moment, I can cause a reboot by hitting ENTER twice. My encounters with this same problem outside of X show that a kernel panic message is displayed on the console screen, the disks are synced, and then a prompt appears saying something along the lines of "Press a key on the console to reboot." In my attempts to tackle the issue last year, I compiled a debug kernel and enabled crash dumps to my swap device (swap = 132MB, main memory = 64MB) via the rc.conf 'dumpdev' option. Surprisingly, no crash dumps resulted when the kernel had its next few panics, so I was unable to obtain a backtrace of the code path. The panic message is basically... Fatal trap 12: page fault while in kernel mode [...] ... with the register values and so forth that are meaningless to post here without some kind of backtrace. Is there any reason why I am unable to get crash dumps? The lock ups appear to occur in four main categories: 1. Using X and Netscape to surf the Web. 2. Heavy disk activity (with and without X active), e.g. untarring large tarballs, compiling large code bases, etc. 3. Executing commands such as sockstat, netstat, ps aux, etc. (with and without X active). The access of kernel memory seems relevant here. 4. Executing reboot(8) -- the hang occurs either immediately after typing the command or just after the mounting of filesystems. The lock ups are the exception rather than the rule, and most of the time I can perform the above operations without incurring any punishment. But they still occur too frequently for comfort (on average of 5-6 times daily). I *really* do want to solve this problem and will very much appreciate any help offered. If there are any more details I can provide that will assist in identifying what's going on, please let me know. Also, I will gladly follow any debugging procedures that may help. [hardware/configuration details] My hardware is in excellent condition. dmesg output and a copy of my kernel configuration file are included at the bottom of this post. I use the popular ICH audio driver available at the following URL: http://www.katsurajima.seya.yokohama.jp/ich/ bash-2.05$ kldstat Id Refs Address Size Name 1 4 0xc0100000 1d4818 kernel 2 1 0xc02d5000 9cc0 agp.ko 3 1 0xc093b000 4000 logo_saver.ko 4 1 0xc0940000 12000 linux.ko As you can see above, I have the AGP kernel module loaded at boot time and Linux binary emulation enabled.
