Hey all, I was asking this back over on fedora-list but had no responses. How do I debug a hung system? My box doesn't (ibm e326 with FC4, x86_64) actually panic and crash so lkcd is of no use(?) kgdb? How about magic sys key ? I can reliably make it hang to a point where the only working operations I can see are a blinking cursor and replies to ping packets. I did see this message once : <3>Debug : Sleeping function called from invalid context at include/linux/rwsem.h:43 in_atomic:(0) irqs_disabled:(1) Yes, I know it's off topic but I've googled and asked elsewhere to no avail. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
