It looks like there may be some source upgrade nits, but my understanding was that if you follow the complete directions in UPDATING, things should generally work well. The only difficulty I ran into upgrading from about 5.1-RELEASE to 5.2-JUSTBEFOREBETA a couple of weeks ago was that although the net 5.2-BETA / contents are much smaller than 5.1, during the upgrade you overlap lots of larger binaries, /rescue, and /lib, and the result is you briefly need more space rather than less space. The box in question was installed as 4.0-CURRENT, and had a very small / file system, and required a bit of manual adjustment to get forward as a result. > 1.

If so, you may wish to recompile your kernel with WITNESS and INVARIANTS turned off and see if that helps. These debugging features are critical during the development process, but also seriously impact performance and might make the difference you're seeing. > 2.

Unfortunately, some classes of hardware/driver failures are very hard to convert to explicitly caught panics, especially where they involve the mechanism by which panics are displayed (system console), or low level memory management, etc. Many developers run with serial consoles so that they can still get access to console debugging information even when in X Windows, etc. Robert N M Watson FreeBSD Core Team, TrustedBSD Projects robert_at_fledge.watson.org Senior Research Scientist, McAfee ResearchReceived on Sat Nov 29 2003 - 08:34:49 UTC
