This bug is not yet fixed, but I just uploaded a change that will mean you
stop getting pestered about it. That change should hit your machines in
about a week after it has gone through testing.
I am well aware that this problem will go away, so reports that it is "fixed"
at that time will be useless. The problem will not be fixed, we will have just
stopped the nagging.
** Description changed:
+ The edac_amd64 module attempts to load on many systems. If the system doesn't have ECC
+ memory, or it is disabled in the BIOS, then the module prints
+ EDAC amd64: WARNING: ECC is NOT currently enabled by the BIOS. Module will NOT be loaded.
+ Either Enable ECC in the BIOS, or use the 'ecc_enable_override' parameter.
+ Might be a BIOS bug, if BIOS says ECC is enabled
+ Use of the override can cause unknown side effects.
+ before failing to load. This won't cause issues for most people that see
+ the message.
+ kerneloops picks this up as kernel problem as the "WARNING:" looks a lot like what
+ you get when using WARN().
+ There are several aspects to this issue:
+ * linux
+ - something attempts to load the module when perhaps it doesn't need to (unclear at this point)
+ - the module looks like it is using WARN() when it isn't, and is arguably more SHOUTY than
+ it needs to be.
+ * kerneloops
+ - picks up this as WARN() when it isn't.
+ - Was accidentally left enabled for the stable release, people shouldn't be getting asked to report
+ this at this point.
+ - Isn't very good at dealing with repeat issues, causing more reports to be sent than are needed.
+ and possibly others as well.
Annotation: Your system might become unstable now and might need to be restarted.
