<P><FONT SIZE=2>Hi,</FONT> </P>
<P><FONT SIZE=2>I've been having kernel oopses with the 2.4.0-test series and am including ksymoops processed output from both test4 and test5 kernels. The same oops happens in later kernels too (I've tested test6 and test7).</FONT></P>
<P><FONT SIZE=2>The scenario is this:</FONT> </P>
<P><FONT SIZE=2>I have an incoming UDP stream at 1mbit. The router marks packets in this stream, according to port ranges, with 3 marks (via iptables v1.1.1). iproute2 builds new routing tables based on these marks, and mplsadm, with the tc patch, is called to build mpls paths using these routing tables. Finally, the 3 egress LSPs are rate limited using tc (cbq classes) to a value less than the ingress rate (ie: I limited each LSP to 200kbit, for an aggregate egress output rate of 6t00kbit). When I start the traffic flowing from our generator, the box panics and freezes quite solidly. If I move the egress rate limiting to another box, it works okay.</FONT></P>
<P><FONT SIZE=2>I copied down the oopses and ran 'ksymoops < oops.txt > oops_proc.txt' and pasted them here. The first is from kernel 2.4.0-test4 and the second from 2.4.0-test5.</FONT></P>
<P><FONT SIZE=2>Cheers!</FONT> <BR><FONT SIZE=2>Jon</FONT> </P> <BR>
