Re: [CentOS] Anyone with RedHat Subscription?
Their "resolution" is: Update to RHEL 7 to get the more recent ethtool output format. You should be able to build a newer ethtool from source (or depending on your NIC manufacturer, they may supply a tool with more recent features. Solarflare, for example, provides 'sfctool', basically new ethtool features for old kernels).

Re: [CentOS] system unresponsive
In the past I've found that the console may have blanked (due to time) and when the system locked up/hung it won't unblank. Booting with "consoleblank=0" on the kernel command line will ensure that whatever is printed to the console (oops, panic, etc) will be there for you to see when you connect. I've had intermittent success in that type of situation with the SysRq key(s), see https://en.wikipedia.org/wiki/Magic_SysRq_key . They do require that you have it configured/enabled ahead of time. If you access the console over a BMC/IPMI KVM session it can be very difficult, if not impossible, to enter the keystroke as well.
