I have now captured a kernel crash. Everything after iput in the second crash was hand-coped, and may suffer from transcription errors, but it was done quite carefully. System has ECC memory and has been very stable, with uptimes in excess of 1 year when kernel upgrades were infrequent (2.5 development). Stock 2.6.6 kernel, config as posted before.
