Try this (meaning that I didn't and think it will accomplish this but didn't test it myself): # dmesg -n5 I always set dmesg -n5 in order to avoid the flood of kernel messages concerning blocked packets from my firewall. But perhaps a different level setting would be needed for your issue. Here is the explanation: The dmesg -nNUMBER sets the level at which the kernel will log messages to the console. The level is less than the number. To avoid logging KERN_INFO 6 or lower must be used. Here is the definitions from the Linux kernel. #define KERN_EMERG "<0>" /* system is unusable */ #define KERN_ALERT "<1>" /* action must be taken immediately */ #define KERN_CRIT "<2>" /* critical conditions */ #define KERN_ERR "<3>" /* error conditions */ #define KERN_WARNING "<4>" /* warning conditions */ #define KERN_NOTICE "<5>" /* normal but significant condition */ #define KERN_INFO "<6>" /* informational */ #define KERN_DEBUG "<7>" /* debug-level messages */ The kernel default is 8 so that all messages are logged to the console. At least one other distro sets this to 3 in /etc/syscontrol/init and so users there never see console messages. Debian doesn't make this policy decision anywhere that I know of and so the level is left unchanged at the default kernel value. I set it in my Shorewall init script since I am using it to block packet messages. Bob
