Description Andreas Kleen 2006-02-22 11:10:51 UTC

We have a lot of machines who spews tens of even hundreds of these
messages at boot. There are also various bug reports from people
complaining about this.

I think the message started with the last ACPICA update.

I'm inclined to just comment that message out. Or does it really
serve any useful purpose? Intel folks, please comment on this.

*** Bug 152263 has been marked as a duplicate of this bug. ***

Comment 2 Andreas Kleen 2006-02-24 12:45:57 UTC

I removed it now since Intel doesn't seem to be attached enough to it
to comment on it.

It's only from memory hotplug, which is a oddball on most systems anyways.

Comment 3 Thomas Renninger 2006-02-27 11:31:49 UTC

The code where this message appears is redundant.
I sent a patch to acpi-devel subject:
acpi_memoryhotplug.c needs not to walk whole namespace twice to register notify handler

I will also attach here.
Shall I add it?

Comment 5 Thomas Renninger 2006-02-27 11:53:57 UTC

Greg is involved into the hotplug stuff a lot.
Can you sign this off and consider it safe to add, Greg?

Comment 6 Greg Kroah-Hartman 2006-02-28 00:49:35 UTC

Sorry, but I'm not involved in memory hotplug at all, and try to stay away
from ACPI as much as I possibly can, so I really can not judge the quality
of this patch enough to add a Signed-off-by: with my name to it.

Please submit it to the acpi development mailing list, they should be
able to judge it properly.

Comment 7 Len Brown 2006-05-15 03:58:30 UTC

re-opening so we can re-assign and get a an up-stream fix in place.

Comment 8 Andreas Jaeger 2007-05-04 07:04:40 UTC

What is the status here?  Shall this one closed as WONTFIX or is it fixed in openSUSE 10.2?

Comment 9 Thomas Renninger 2007-05-04 07:30:55 UTC

It's fixed with this patched, also in 10.1 branch, we simply removed the wrong error msg:
