Quite often, when I'm using X/GNOME and have some heavy CPU intensive task in the background (i.e. make world) something wrong happens with the kernel - all commans that use kvm stop working (top, systat etc) and system feels increadible slow, especially when switching from one task to another. There is nothing in kernel logs about that. For example `systat -vm' starts with all values being blank, then waits couple of seconds and prints "The alternate system clock has died! Reverting to ``pigs'' display." I've never observed such problem before and is ready to perform any debugging necessary if somebody have any ideas about how to do it. -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
