>Environment:
Arakis 4.0 Release FreeBSD 4.0 Release #8 Sat May 6
root@Arakis:/usr/src/sys/compile/NEXUS-6 i386
>Description:
compile into the kernel the following:
options PPP_DEFLATE
when using xload, 50% utilization can be seen, maybe 100% on one cpu, this is a known issue on my motherboard proc combination on win2k
ASUS P2B-D 2 400Mhz P-II
Bios Rev 12
I can send the kernel config if needed
>How-To-Repeat:
add the options PPP_DEFLATE in the kernel to see the cpu(s) race, 
remove the line, recompile, etc and the problem goes  away
>Fix:
remove the line, do not use BSD deflation
