SMP problems?
I've seen problems that I have avoided by backing out my second
processor.
Machine: sparc-20
OS: 2.2.14
CPUs: 2
Using the sparc as for NAT to other machines. When it had
both eth0 (10MB/s) and eth1 (adsl+pppoe) going good, pppoe
would say that it found a bad checksum, and drop the line.
At the same time, this was deposited in kern.log. This happened
many times until I pulled the second CPU and has not happened since.
Does anyone know if there are still problems with SMP in sparc?
