Hi, I've been running 5.1-RELEASE for quite some time on my dual PIII 333Mhz Micron PC with 384MB of RAM and 670MB of swap. Its a little low on memory for what I'm now doing with it though, so I added 256MB of RAM. The new RAM gets recognized, and there are no obvious errors on the console or in the logs, but every little thing drives the CPU utilization through the roof and the system is unusable. Even just typing "man ls" triggers it, never mind trying to run ssh. I remove the RAM, and it goes back to normal. I'm using a kernel with these relevent settings: cpu I686_CPU options SCHED_ULE options COMPAT_43 options COMPAT_FREEBSD4 options _KPOSIX_PRIORITY_SCHEDULING options SMP options APIC_IO options LAZY_SWITCH There are other settings, but these are the only ones that might be related, I'm guessing. Has anyone seen anything similar to this? I've searched google as well as the mailing list archives and can't really find anything similar. Any help would be greatly appreciated. Thanks in advance, rgr -- Richard G. Roberto rgr@dedlegend.com
