[PLUTO-help] Kernel bug

[Cristian Rotesi]

Ciao a tutti,
nella mia azienda ho un file server RH 7.3 kernel 2.4.18 con supporto
smp (la macchina ha 2 processori).
Il 27 aprile tentando di accedere tramite ssh si piantava; sono andato
sulla macchina e si piantava quando premevo invio dopo aver immesso
l'userid non facendomi nemmeno entrare.
Ho riavviato (reset) e questo è l'output del file messages:

Dovrebbe essere un bug del kernel!!!
Qualcuno sa dirmi da che cosa può dipendere???

Grazie a tutti!
