The fault information scrolls off the top of the console... I have /usr/obj mounted on a ccd. Less then 2 minutes into a make world, the console shows a ccd problem, error 5. Page fault in the kernel. The above problem is repeatable (but the machine is not infront of me right now). I unmounted the /usr/obj ccd filesystem, and am running a make world onto the /usr system which is not a ccd and things seem to work fine (so far). It may be monday before I can get a kernel rebuilt with the debugger enabled. This is a single processor machine, UP kernel, sources current as of 11:30am EST. No error information is written to syslog. -John -- dmesg Copyright (c) 1992-2000 The FreeBSD Project.
