(can be removed - no effect) 8 Meg of RAM. The hard disk was completely wiped during multiple installations. Kernel can be the stock kernel, a "make world" kernel, or a custom kernel. >Description: [FDIV009] SNAP-032295 is less stable than the previous SNAP. I get system lockups during kernel builds, ls -alR | more, even grep commnds. This same system ran SNAP-021095 for a month without problems. The system also ran 2.0 and 1.1.5.1 without problems. When I rebuild the kernel, typically three to six drivers get recompiled. During this process, the system will lockup an average of one time per build. I have had to restart the same build three times to make it all the way through, and then ten minutes later a recompile of the same files goes through without incident. The lockup is just that - no panic. The system simply goes dead, no activity, Numlock and Capslock no longer toggle when you push keys. Pings are not recognized. I have removed and reseated RAM, processor, all cards, and finally replaced all the RAM and the problem doesn't go away. I finally moved the hard disk to a similar system (almost identical configuration that has been running SNAP-021095 since it was available with no problems) and now the other system randomly lockups. I assume it is either a memory management problem or a problem with the wd disk driver. It will not lockup if the system isn't doing anything. It has to be crunching to cause the problem to show itself. In fact, I wrote this report by telneting from a SNAP-032295 system to a 1.1.5.1 system that was otherwise idle. While typing this note, cron ran /etc/daily on the 032295 system and locked the system up. Nothing else was running and there are no other users. >How-To-Repeat: Here it is easy. Give the system something disk-intensive to do. >Fix: *END* >Audit-Trail: >Unformatted:
