I also have to mention that this happens when I run RTLinux application (so this kernel contains RTL patch) and DRI is activated. I'm not necessarily saing this is linux kernel bug as it could be the problem of RTL patch or some DRM issue - however as I've no idea what is the reason for this NMI lockup on one of my CPU I'm posting it here. System is BP6 2x480MHz Celereon. Also this is probably the first time I've seen that the system went smoothly to the console mode and displayed this oops message. (I've rewritten important parts on paper by hand soI hope there are no mistakes) With previous kernel the typical scenario is that machine is frozen and in the mouse position there is white box probably with this size 64x64 pixels. If anyone wants to know more details feel free to ask. $ /var/tmp/ksymoops-2.3.4/ksymoops oops ksymoops 2.3.4 on i686 2.4.1-pre12-RTL3.11b. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.1-pre12-RTL3.11b/ (default) -m /usr/src/linux/System.map (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
