Seems this was not available when I searched for a list of vulnerable CPUs. I'm not sure about Xeon W5590, it is on the list but the spectre poc does not read anything. For meltdown, somewhere in the news I read that all Intel CPUs since 1995 are vulnerable, which is rubbish. The paper says Intel CPUs since 2010. I tried different approaches to get meltdown working on Xeon E5420 and W5590 (launched Q3/2009) ... just nothing. So I am really happy that my 10 HP Proliant DL360 G5 are still safe. At least for me, a lot of panic for nothing.
