Hello Gents, Sorry I didn't include all the version info etc because what I really wanted was some general guidelines on kernel debugging so I could check into this myself. However as you're all so kind and want to know :) No custom modules at all. It's out of the box. And the problem occurs with both SMP and UP kernels of version 2.6.11-1.1369_FC4 #1 Thu Jun 2 22:56:33 EDT 2005 x86_64 x86_64 x86_64. All I need to do is start an rsync over ssh from another machine of 8GB (many files) and after a minute or two she's popped. The closest thing to a trace I've managed to see is : <3>Debug : Sleeping function called from invalid context at include/linux/rwsem.h:43 in_atomic:(0) irqs_disabled:(1) And I just saw something like this : "Warning lost too many ticks Your time source is instable or some driver is hogging interrupts." Any ideas lads?
