I saw this once about 5 minutes after booting a kernel and then didn't see it again for another 5 days or so until it happen today. I looked into it and I concluded that it's pretty much a "generic" problem that has existed with the read-/write-semaphores since their inception. The problem also shows on x86 and Alan Modra is working on a generic solution to the problem. Since it's already being addressed, I'm not planning to spend a lot of time on this and will probably just wait for 2.4.4 to get this fixed for real. In the meantime, expect occasional crashes with 2.4.3. If you don't like this, you may want to stay with 2.4.2 for now (or scream loudly and we can look into fixing it for ia64 before 2.4.4 shows up). --david
