Bugzilla Bug 217323

When I compile recent g-s (or a vanilla kernel with the UAC patch added) on
alpha, I get multiple sysctl/uac related messages (see attached dmesgt.txt).

This happens on the following kernels:
2.6.24.4
2.6.24-gentoo-r4
2.6.24-gentoo-r5
2.6.25-rc8

It doesn't happen on these:
2.6.23-gentoo-r9
2.6.23.17

Note that the *functionality* added by the UAC patch is working just fine in
all cases.

updated alpha uac patch

Here's a updated alpha uac patch I created from dsd's instructions. It's
untested. 

Can you apply it against vanilla-2.6.24.4 and let me know the results?

Vanilla 2.6.24.4 with the patch applied doesn't compile:

New updated patch 

Thank-you, Tobias, for the alpha access. This one actually compiles.

boot messages for patch #3

It now compiles, but there still are similar error messages (yet slightly
different ones) as initially.

Created an attachment (id=149614) [details]
new patch number 4

Please test when you have a chance.

That seems to have done it. No more strange messages and the sysctl works as
advertised. Thanks a bunch!

fixed in gentoo-sources-2.6.24-r6 / genpatches-2.6.24-7, thanks for the testing
