Same on x86:

I could reproduce it on x86_64. Same issue

Using the config provided by openvz for the rhel6 kernel version at http://download.openvz.org/kernel/branches/rhel6-2.6.32/042stab049.6/configs/ can be compiled without issues. 

For me this looks like there is one kernel setting that causes this issues. I did try to find this config by adding more and more options to my config to figues out the config switch, but I did not succeed. I'm now trying to strip down the provided option until it fails, hoping that it will provide me with some insight.

[Comment 4 Alexander Zubkov 2012-03-24 17:16:29 UTC]

It looks like it compiles well with CONFIG_LOCKUP_DETECTOR, in that case this piece of code is dropped by preprocessor.

# grep CONFIG_LOCKUP_DETECTOR linux-2.6.32-openvz-049.6/.config
CONFIG_LOCKUP_DETECTOR=y

and doesn't compile for me.

Error remains the same? Because there seems to be many other restrictions in compiling this kernel. I have also submitted couple of bugs. But there's more.

Yes. I didn't change anything since I opened this bug.

[Comment 8 Alexander Zubkov 2012-03-26 13:45:00 UTC]

Hmm... May be, may be. Looks like I was having some other error with alike keywords. :)

[Comment 9 Vladimir Berezhnoy 2012-04-04 03:21:15 UTC]

Having the same issues. Was anyone able to figure out which options is required?

[Comment 10 Per Pascal Seeland 2012-04-05 10:47:58 UTC]

I'm still working on removing config options until it stops compiling. In case anybody has any better suggestion, I would be glad to here it, as removing an option and wait for recompile is something that takes ages.

[Comment 11 Peter Volkov (RETIRED) 2012-05-03 12:32:48 UTC]

Guys, to be on the same side: upstream is unable to handle all build failures since most of them come from rhel patchset others are due to unimplemented features with specific configuration in openvz. I strongly suggest using .config from openvz wiki and tune it to your needs (disable unnecessary modules and compile in features you may need). You may try to report build issues upstream and sometimes they incorporate fixes into their patchset. I did this long time, but ... found much easier to use .config from upstream as new options appear broken with new rhel revision. I'll close this bug as upstream.

If you switch this on in the kernel config the problem is disappear:

Symbol: HARDLOCKUP_DETECTOR Location:
