Hi again, Ok, here are some LOR's that occurred today on the machine before it paniced and wedged. The LOR's are not yet listed on the LOR page, so I cc: Bjoern. The panic and subsequent system wedge did not happen immediately after the LORs, the system continued to run for a while, but only for short while after the second LOR. Important INFO: I cvsuped and built new world and kernel (in single user mode, the system appears to be able to do some work in single user) of _today_. I hoped the problem might go away. I also removed KVA_PAGES=512 from kernel config, so default KVA_PAGES apply. It apparently did not help.
