The link is slightly broken, I've found the patch here: http://www.watson.org/~robert/freebsd/20061230-tcp_pcb_fix.diff Applied, recompiled the kernel - no more panic :) Thanks Robert nad Max. If there's anything else needed let me know. Karol P.S. out of curiosity - now that I have configured kernel with DDB and KDB options, is there any performance penalty of running such kernel? -- Karol Kwiatkowski <freebsd at orchid dot homeunix dot org> OpenPGP: http://www.orchid.homeunix.org/carlos/gpg/0x06E09309.asc [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFlpSOezeoPAwGIYsRCOoDAKCmzq+npho6X5rYq3mkKtrDRt+iqQCfeAOg 7Bf8u80jawg+PsImPFDTdYI= =w1aF -----END PGP SIGNATURE-----
