Disabling IRQ #16

Post autor: starach »

Cześć,

Mam serwer dedykowany świeżo po reinstalacji do której zmusił mnie bardzo dziwny błąd karty sieciowej, ale ja nie o tym. Krótko po wpisaniu komendy
apt-get install postfix postfix-mysql dovecot-core dovecot-imapd dovecot-pop3d dovecot-lmtpd dovecot-mysql mysql-server
Dostałem komunikat:
$Message from syslogd@rptr at Mar 29 12:10:23 ...
kernel:[134930.949734] Disabling IRQ #16
Oprócz serwera usługi pocztowej mam jeszcze na serwerze zainstalowany apache2 i php5

Co ten komunikat znaczy? Czy to powód do niepokoju?
