I should mention that this box is now running under semi-heavy load 24/7 as my do-it-all server with SMP and oldcard in 4.2-BETA. (i.e. load average 2.x, disk constant output 200k/sec.) What happens when the box crashed in -CURRENT is that: 1. boot 2. running fine 3. Do anything useful that fork()'s 4. thousands of the same fork()'s spawns again and again in extraordinary speed. (I wrote a script that automatically runs Apache's "ad" http benchmark app. While the script runs, it sends "killall -9 httpd" as fast as /bin/sh can send it. The machine still dies, but lives only a few minutes longer.) 5. box dies due to heavy load, hard lock, not able to break to ddb/gdb, no response to anything. It ran fine with an UP kernel in 2000102x-CURRENT without the above problem. | > This is an Abit BP6 box, one that I think is the same as your box. | | Yes, that's correct.
