Hi.
On my install of openSUSE 12.3 RC2 after a reboot I have:
> /sbin/sysctl kernel.printk
kernel.printk = 1 4 1 7
Here console loglevel is 1, meaning only very important stuff is printed.
However after resuming from either sleep or hibernation I have:
> /sbin/sysctl kernel.printk
kernel.printk = 5 4 1 7
Console loglevel is now 5, which means that for example firewall events (which happen fairly often) get sent to the ttys (ctrl+alt+f1,2,3…), rendering them pretty much useless.
Would this be considered a bug? I assume it isn’t the intention that the ttys be flooded with firewall logs, and it seems strange that the loglevel should change after resuming from sleep.
I also think I’ve experienced this in openSUSE 12.2, but I don’t have an installation to test it on right now.
