next in thread | raw e-mail | index | archive | help
Hi
I have experienced several page faults this month with the last from a
19APR2008 source build.
A debug session, (today's) dmesg and kernel config file (diff between
GENERIC and site kernel config) are listed below. Let me know if I can
provide further information.
