The oops ocures only when the kernel is build with SMP and HT support, in UP mode the oops doesn't occur!
I have a 2.6.10 kernel with SMP and HT compiled kernel, I have a P4 3GHz with HT
a have a VPN server with pppd and pptpd(poptop) and and average of 130
simultanious connections, the oops doesn't occur at a particular number
of simulationus VPN connection.I can build a kernel with debugging enabled or something to help to track th
source of the problem. Please CC as I am not subscribed to this mailing list.
