It can be found here: http://dcn.infos.ru/~bugman/bootlog.txt I have also put there output of mptable. At a first glance, there are many strange things (e.g. a lot of failures at various places) in this log file, but I don't know which are relevant to the problem :-). Also observe two messages in the end of the file: Jan 12 09:42:04 firewall kernel: arp: 10.0.103.6 is on xl0 but got reply from 00:0e:0c:4d:47:d2 on xl1 Jan 12 09:42:04 firewall kernel: arp: 10.0.103.6 is on xl0 but got reply from 00:0e:0c:4d:47:d2 on xl2 This means that xl1 and xl2 can receive some data. However, with both patches installed they cannot send any data. If it can help you, I can give you root access to this box. With best regards, P. Trifonov
