Source: linux-2.6 Version: 2.6.32-45 Hi,
we hit the above kernel panic twice in two days. There is a bugfix in upstream stable, but it did not make it to 2.6.32, just later kernels: http://git.kernel.org/?p=linux/kernel/git/davem/net- next.git;a=commit;h=8f49c2703b33519aaaccc63f571b465b9d2b3a2d For completeness follows the trace. Thanks, Carsten Aug 15 20:38:33 lb01 kernel: [71032.540454] ------------[ cut here ]------------ Aug 15 20:38:33 lb01 kernel: [71032.544153] kernel BUG at /build/buildd- linux-2.6_2.6.32-45-i386- yQfQSv/linux-2.6-2.6.32/debian/build/source_i386_none/net/ipv4/tcp_ipv4.c:415!
