Previously, init was triggering a wait queue panic in the > scheduler. I forget that if you are not on the BitKeeper mailing list you don't see the updates people make. Wolfgang sent me a stack backtrace that pointed right to a problem in the uart driver with wait queues. They were not initialized properly (actually, not at all :-), so you would get erratic behavior for any type of uart open/close. This was fixed a couple of days ago. This affects both 8xx and 8260, so suck down the latest 2.4.0 sources and give them a test. Now, I will do some 8260 updates, hopefully to fix that irritating Ethernet bug and the timer stuff you sent me. I'll try to be better about posting update message to this list (if people want that info). -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
