Hi - So I have this wierd problem, which is duplicated on 3 identical
machines, where I get a bunch of "bmc_io_wait fails" messages (see the
end of the dmesg).  The longer the machine is on, the more messages get
tacked on. I'm wondering what this could be. Any ideas/hints?

For the curious, the machines have bios rev. a20, 3.35 drac and 1.01
backplane firmware.

Thanks,
Okan
