Greetings,
I've hit a reproducable networking Oops with vanilla 2.4.22; decoded Oops
below. I'm able to reproduce the Oops using httperf:
httperf --hog --server ryantest --uri /speed_test --num-conn 500 \
--timeout 5
Where speed_test is a 76M file. It gets through about 23 of the
requests then the kernel Oopses. Any input is greatly appreciated, and I'm
available to test any patches.
