So there are two bugs/problems here: whatever is causing ACPI to behave this way, and then the fact that UMA is failing to deal properly with its misbehavior.We had the machines running with ACPI disabled for a week or so, and we were still getting these panics, but I'll disable it again in the BIOS to make sure.Alternatively, that we have a bug in the way statistics are handled. If you can generate a coredump, it would be quite useful to be able to run umstat (src/tools/tools/umastat in HEAD) on it. The tool probably needs a bit of tweaking to run on the core dump -- in particular, the first and second arguments of kvm_open() need to be the name of the kernel and dumpfile, rather than NULL. This would help confirm what actual state UMA is in.So far, the machines always just hang instead of dumping core; I'll see if I can get them to write a dump.
On two of the three boxes, the panics have not happened for a week.On the one I disabled ACPI on, no panics were seen for a week as well, so I enabled it again. Within an hour, the panic occurred. call doadump just hangs, so I won't be able to run umastat. I'll try to kick the box via the IPMI card and wait for the next panic.
