I know I've ranted before, but on Penguin's high-end compute rack mount
servers, with, I think, an H8QG m/b, running 64-cores, we've gotten some
where a heavy compute user process has crashed the system, and we even
canned a script and put that on a fresh, basic CentOS install, and sent it
back, and Penguin's replaced m/b's. Several of them. Some more than once,

And then there's the engineering, where for two of the DIMMs, I need to
unplug the main connector from the PSU, because that's the only way to
pull the ears down far enough to remove the DIMMS.

We won't mention all the DIMMs that they've replaced (he says, meaning to
call them about one system *again*....)
