chi-node-05 has hardware (memory, disk) issues

when trying to install chi-node-05 (#40365 (closed)), i had many problems. but most worrying is what seems to be a hardware issue.

the iDRAC says:

Persistent correctable memory errors detected on a memory device at location DIMM_A2.

I believe DIMM_A5 also has issues based on BIOS warnings at boot.

In general, the console is barely useable and i am not sure the machine will be reliable in any way. need to talk with cymru about this.

Update: there's also warnings from smartd...
