I'm trying to install openvz-sources (sys-kernel/openvz-sources-028.027) on my desktop machine. the kernel configuration and installation is correct. I can boot under the new kernel and manage openvz virtual machines from the command line. all the drivers for my machine load correctly. but when I try to compile the closed source ati-drivers (x11-drivers/ati-drivers-8.37.6-r1, this is a desktop machine, remember), the compile fail with the following message: WARNING: "find_task_by_pid" [/var/tmp/portage/x11-drivers/ati-drivers-8.37.6-r1/work/common/lib/modules/fglrx/build_mod/2.6.x/fglrx.ko] undefined! !!!

I searched on google and I seem to be the first to have this problem. I don't even know if this is a bug or a problem with my machine. however, everything work with everything else on both kernels, and I can compile ati-drivers with my current kernel (gentoo-sources-2.6.20-r8) Reproducible: Always Steps to Reproduce:

That's just a warning, not the compile error. You need to post more lines above.
well, it's the only line that seems wrong. I attach the build log below

Shrug; does any other version of ati-drivers compile?
well... it compiles with ati-drivers-8.35.5 (the latest stable). I should have tested that first :-(. In fact, I was forced to switch to unstable ati-drivers a while ago and never minded to switch back to stable after that... ok then. I can use the stable ati-drivers and this solves my problem. now I can't tell why 8.37.6 doesn't compile on kernel 2.6.18...

A complete build log is located at '/var/tmp/portage/x11-drivers/ati-drivers-8.37.6-r1/temp/build.log'.
The issue is that the openvz patch removes the find_task_by_pid macro, which ati-drivers is now depending on. The solution is to apply a fix to the upstream openvz patch so that this macro still continues to exist for compatibility reasons. Will see if I can get a patch for this.
OK, here is the solution. The openvz patch undefines find_task_by_pid and creates two new macros: find_task_by_pid_ve and find_task_by_pid_all. It also updates all references in the kernel source code to refer to the new macros. The problem occurs when other kernel modules use these macros, in which case they break. Since modules are typically not directly used in your VE's, I use the following solution to get the ati-drivers to install and build (tested against ati-drivers 8.40.4). Add the following to include/linux/sched.h: // drobbins hackzor #define find_task_by_pid(nr) find_task_by_pid_type_all(PIDTYPE_PID, nr) extern struct task_struct *find_task_by_pid_type_all(int type, int pid); This will give any modules that call the find_task_by_pid() macro the default behavior. This may not be appropriate for all kernel modules, especially those that need to be aware of VE's. But it is likely to be correct 99% of the time.
Thank you all for report, and Daniel for suggested fix. This bug should be fixed in 2.6.18.028.049. Note, versioning changed so to emerge this new version you have to run: emerge =sys-kernel/openvz-sources-2.6.18.028.049 Note 2: I did not manage to check that fix really works, as ati binary drivers do not work with the recent xorg. So if this bug is not fixed, reopen, please. Also I'm going to mark this new kernel stable in next few days, so if you have some time, please, try it and report everything you encounter.
Yup, the bug was fixed in 028stab049, here is some more info. Upstream bug report: http://bugzilla.openvz.org/show_bug.cgi?id=634 GIT commit: http://git.openvz.org/?p=linux-2.6.18-openvz;a=commit;h=3d422a091cd4c871ca2781c0e9a6fcaf5180f77e
