Have you tried to build development-sources with ACPI? If you haven't, could you please check it out? Could you try development-sources-2.6.8.1 please and if you still get this issue can you reopen this bug? Thanks! This bug looks definitely like the bug described in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125841 and also in http://bugzilla.kernel.org/show_bug.cgi?id=2941 Looks like especially boards with Intel's 865 chipset and CPUs supporting hyperthreading are affected. I am also suffering from this bug since i own a Intel D865GBF board with 2.6GHz HT CPU. The cause of the problem seems to be identified and a patch which should make you happy exists. Just follow the first link above and take a look at comment #78. I planned to apply and test the patch today - I'm pretty sure it will work - but I don't want to patch every single new gentoo-dev-source over and over again (the problem exists already for quite some time). You either have to wait for 2.6.9 (which will have the mentioned patch applied)or apply the patch yourselve or convince the maintainer of gentoo-dev-sources to release a fixed version ... The latest kernel version that I tested and that shows the bug is 2.6.8.1, didn' try 2.6.8.2 yet. I will test 2.6.8.2 and the reopen the bug if the problem persists.

Cheers, Andreas Oops, sorry for the double post. Dunno what happened. Ok, so after having tested 2.6.8.2 I can confirm that the problem persists. Someone will have to apply that patch, please. Andreas Which patch? I checked the 2.6.9 tree (as of 2.6.8.1-ck4) and neither of the following two patches have been merged. https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=102665&action=view http://bugzilla.kernel.org/attachment.cgi?id=3508&action=view Please have a look at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125841 and specifically at comment #78: ===================================================================== Additional Comment #78 From Len Brown on 2004-08-16 21:23 ------- This bug is also reported here: http://bugzilla.kernel.org/show_bug.cgi?id=2941 and the fix in (comment #73) is in 2.6.9 tree. ===================================================================== Doesn't this mean that the patch is going to be merged in 2.6.9? Or is it Fedora's 2.6.9? I don't know. Anyway, this evening I applied the patch from http://bugzilla.kernel.org/attachment.cgi?id=3508&action=view to my gentoo-dev-sources-2.6.8-r2 sources and (after having to apply one of the hunks manually bacause of differing base kernel versions) and my problems vanished completely. That means, with ACPI enabled, now both sibling of the HT CPU are detected and the machine works like a charm. Therefore I think it would be a very good idea to have that patch integrated into gentoo-dev-sources. Cheers, Andreas Ok, this now appears to be in -mm so I'll get this sent up for future releases. In gentoo-dev-sources-2.6.8-r5 Considering removing this patch, its causing other problems (see bugs #66613 and 66723). My worry is that the livecd uses this kernel, and 2004.3 deadline is coming up quickly. With an issue like this (the fix creates another problem) I'd rather leave the fix out so that any problems experienced aren't our (Gentoo's) fault. |
