Openbsd 4.6 kernel fault sshd

Nicolas le Falher
Bonjour.

Sur une soekris net4501, avec OpenBSD 4.6 installC) via pxe (bsd.rd),
je recontre un kernel fault systC)matique du deamon sshd.

Rarement dans une utilisation quotidienne.
A tous les coup lors d'un appel au port tty01 avec minicom ou cu.

Le port tty01 (com2) C  C)tC) testC) pendant 24h avec minicom et cu via le
port tty00 (com0) avec succC(s.
Par contre des que j'essaie de consulter le port tty01 via sshd, j'ai
un kernel fault systC)matique.

S'il vous manque des informations, n'hC)sitez pas.
Cdt.

Voici les dC)tails :

ddb> show panic
the kernel did not panic
