Erm.. with only a subject line to go on who knows. The bug with route cache
loss and 2.0.x only applies to firewall boxes blocking icmp packets or
all packets and getting icmp entries. It and various other network bugs are
fixed in 2.0.23ac#2. Please test with that before submitting any network
bug reports [I've no idea when Linus is going to release 2.0.24, but if
he takes too long Im going to release a 2.0.24unoff and he can sound off
all he likes]. All the existing 2.0.x kernels are to buggy for 2.1.x to
be the main goal.
