I/O. - This happened today three times in row - I has happened before, but not this frequently - There is nothing special on console - It apparently happens on very loaded systems only >How-To-Repeat: I wish I knew. It could be some program waking it up, as it happened this often today. I don't know what program that would be, there are 50 users logged in typical. innd and apache are the biggest hogs. I can't put kernel debugger in this machine, as I need it to reboot after a panic, but I guess it would be very useful to somehow to get it panic by force to get a crash dump, so that when it deadlocks, I could provide more information about the problem. >Fix: >Audit-Trail: >Unformatted:
