EDAC amd64: WARNING: ECC is NOT currently enabled by the BIOS. Module will NOT be loaded.

[nixy]

I was using the rt-kernel, yet today's update (October 16, 2009) installed a generic kernel, which does not work:

udevadm trigger is not permitted while udev is unconfigured.
Svgalib: cannot open /dev/mem.
Gave up waiting for root device.
...

So, after restarting the computer the boot menu appears, and from that I pick the linux-rt kernel I used before the update. Now I get this warning regarding ECC not being enabled.

I hope this was helpful. Thanks!

I'm getting the same thing. Karmic 64

I have had exactly the same problem (Karmic x86_64):

Update to 2.6.31-14-generic gave that same /dev/mem error message. I booted off the old kernel and dpkg-reconfigured linux-image-2.6.31-14-generic and that got it working again!? I have no idea why it failed in the first place..

I am getting the EDAC warning on this kernel, and on 2.6.31-9-rt also.

Jerry and donarntz,

Could you confirm that -generic kernel is also affected?

Thanks!

I'm a linux newbie, so I'm of limited help. I think I'm using the generic kernel on karmic 64. All I know is that its not booting. I have to use the earlier kernel.

Yes, kernel 2.6.31-14-generic seems to be affected as well: a crash report appears and says "..system might become unstable now and might need to be restarted."

Hi,

Could you check if this bug is a duplicate of the #452772?
