GHES: Failed to read error status
It appears that there's a problem with Dell poweredge servers and GHES judging by the bug reports at
https://bugzilla.redhat.com/show_bug.cgi?id=746755
https://bugs.launchpad.net/ubuntu/+bug/881164
Is this likely to be something that Dell need to fix in a firmware update, or something that the code needs to accomodate ?

I think one problem was that in 2.6.38 the kernel saw HEST/GHES was supported and just tried to communicate with it. Unfortunately the kernel forgot to tell the BIOS that it supports firmware first mode, so in this case the firmware is probably blocking the GHES access and the kernel is confused why.
The following commits resolved that issue (which may not entirely fix the problem, but might move it along).
9fb0bfe ACPI, APEI, Add WHEA _OSC support
b3b46d7 APEI: Fix WHEA _OSC call
The second one in particular was noticed by Dell. Though I recall that we needed to update the firmware to get Dell boxes working, but that was probably for EINJ.
Cheers,
Don
